Page 10
The license is issued via a digital license code in the form of the file hbedv.key. This
digital license code is the key to your personal license. It contains exact details of which
programs are licensed to you and for what period of time. A digital license code can
therefore also contain the license for more than one product.
If you purchased your AntiVir program on the Internet, or via a program CD/DVD, the
digital license code is sent to you by email. You can load the license key during
installation of the program or install it later in License Manager.
3.3.1 License Manager
The Avira AntiVir Professional License Manager enables very simple installation of the
Avira AntiVir Professional license.
Avira AntiVir Professional License Manager
Product information
You can install the license by selecting the license file in your file manager or in the
activation email with a double click and following the relevant instructions on the
screen.
Note
The Avira AntiVir Professional License Manager automatically copies the corresponding
license in the relevant product folder. If a license already exists, a note appears as to
whether the existing license file is to be replaced. In this case the existing file is
overwritten by the new license file.

For the Internet-based installation of the program, an installation program is provided
that loads the current program file prior to installation by the Avira GmbH web servers.
This process ensures that your AntiVir program is installed with the latest virus
definition file.
Installation with an installation package:
The installation package contains both the installation program and all necessary
program files. No language selection for your AntiVir program is available for
installation with an installation package. We recommend that you carry out an update of
the virus definition file after installation.

programs.
Select your AntiVir program and click Change. In the welcome dialog of the program,

4.3 Installation modules
In a user-defined installation or a change installation, the following installation modules
can be selected, added or removed.
– AntiVir Professional
This module contains all components required for successful installation of your
AntiVir program.
– AntiVir Guard
The AntiVir Guard runs in the background. It monitors and repairs, if possible,
files during operations such as open, write and copy in on-access mode.
Whenever a user carries out a file operation (e.g. load document, execute, copy),
the AntiVir program automatically scans the file. Renaming a file does not trigger
a scan by AntiVir Guard.
10
Page 16
Installation and uninstallation
– AntiVir ProActiv
The ProActiv component monitors application actions and alerts users to
suspicious application behavior. This behavior-based recognition enables you to
protect yourself against unknown malware. The ProActiv component is
integrated into AntiVir Guard.
– AntiVir MailGuard
MailGuard is the interface between your computer and the email server from
which your email program (email client) downloads emails. MailGuard is
connected as a so-called proxy between the email program and the email server.
All incoming emails are routed through this proxy, scanned for viruses and
unwanted programs and forwarded to your email program. Depending on the
configuration, the program processes the affected emails automatically or asks
the user for a certain action.
– AntiVir WebGuard
When surfing the Internet, you are using your web browser to request data from
a web server. The data transferred from the web server (HTML files, script and
image files, Flash files, video and music streams, etc.) will normally be moved
directly into the browser cache for display in the web browser, meaning that an
on-access scan as performed by AntiVir Guard is not possible. This could allow
viruses and unwanted programs to access your computer system. WebGuard is
what is known as an HTTP proxy which monitors the ports used for data transfer
(80, 8080, 3128) and scans the transferred data for viruses and unwanted
programs. Depending on the configuration, the program may process the affected
files automatically or prompt the user for a specific action.
– Avira FireWall:
Avira FireWall controls communication to and from your computer. It permits or
denies communications based on security policies.
– AntiVir Rootkit Protection
AntiVir Rootkit Protection checks whether software is already installed on your
computer that can no longer be detected with conventional methods of malware
protection after penetrating the computer system.
– Shell Extension
The Shell Extension generates an entry ‘Scan selected files with AntiVir’ in the
context menu of the Windows Explorer (right-hand mouse button). With this
entry you can directly scan files or directories.
4.4 Uninstallation
If you wish to remove the AntiVir program from your computer, you can use the option
Add or Remove Programs to Change/Remove programs in the Windows Control
Panel.
To uninstall your AntiVir program (e.g. in Windows XP and Windows Vista):
Open the Control Panel via the Windows Start menu.
Double click on Programs (Windows XP: Software).
Select your AntiVir program in the list and click Remove.
You will be asked if you really want to remove the program.
11
Page 17
Avira AntiVir Professional
Click Yes to confirm.
You will be asked if you want to re-enable Windows FireWall (the Avira FireWall
is disabled).
Click Yes to confirm.
All components of the program are removed.
Click on Finish to complete uninstallation.
Where appropriate, a dialog box appears recommending that your computer be
restarted.
Click Yes to confirm.
The AntiVir program is uninstalled and all directories, files and registry entries
for the program are deleted when your computer is restarted.
4.5 Installation and uninstallation on the network
To simplify installation of AntiVir programs on a network of multiple client computers
for the system administrator, your AntiVir program has a special procedure for the
initial installation and the change installation.
For automatic installation, the setup program works with the control file setup.inf. The
setup program (presetup.exe) is contained in the program’s installation package.
Installation is started with a script or batch file and all necessary information is obtained
from the control file. The script commands therefore replace the usual manual inputs
during installation.
Note
Please note that a license file is obligatory for initial installation on the network.

alert, you will receive an alert whenever a virus is detected, indicating the action
performed.
Action options for the Guard:
– Interactive
In interactive action mode, data access is denied and a desktop notification is
displayed. In the desktop notification you can remove the malware detected or
transfer the malware to the Scanner component using the Details button for further
virus management. The Scanner opens a window containing notification of the
detection, which gives you various options for managing the affected file via a
context menu (see Detection::Scanner):
– Automatic
In automatic action mode, when a virus or unwanted program is detected, the action
you selected in this area is executed automatically. If you enable the option Display
alert, you will receive a desktop notification whenever a virus is detected.
Action options for MailGuard, WebGuard:
– Interactive
In interactive action mode, if a virus or unwanted program is detected, a dialog box
appears in which you can select what to do with the infected object. This option is
enabled as the default setting.
– Automatic
In automatic action mode, when a virus or unwanted program is detected the action
you selected in this area is executed automatically. If you enable the Display alert

WebGuard) reporting the detection, and the type of malware detected.
Actions of the Scanner and the Guard (not ProActiv detections):
– Repair
The file is repaired.
32
This option is only available if the infected file can be repaired.
– Move to quarantine
The file is packaged into a special format (*.qua) and moved to the Quarantine
directory INFECTED on your hard disk, so that direct access is no longer possible.
Files in this directory can be repaired in Quarantine at a later data or, if necessary,
sent to Avira GmbH.
– Delete
Page 38
Overview of AntiVir Professional
The file will be deleted. This process is much quicker than overwrite and delete. If a
boot sector virus is detected, this can be deleted by deleting the boot sector. A new
boot sector is written.
– Overwrite and delete
The file is overwritten with a default template and then deleted. It cannot be
restored.
– Rename
The file is renamed with a *.vir extension. Direct access to these files (e.g. with
double-click) is therefore no longer possible. Files can be repaired and given their
original name at a later time.
– Ignore
No further action is taken. The infected file remains active on your computer.
Warning
This could result in loss of data and damage to the operating system! Only select the
Ignore option in exceptional cases.
– Always ignore
Action option for Guard detections: No further action is taken by Guard. Access to
the file is permitted. All further access to this file is permitted and no further
notifications will be provided until the computer is restarted or the virus definition
file is updated.
– Copy to quarantine
Action option for a rootkit detection: The detection is copied to quarantine.
– Repair boot sector | Download repair tool
Action options when infected boot sectors are detected: A number of options are
available for repairing infected diskette drives. If your AntiVir program is unable to
perform the repair, you can download a special tool for detecting and removing boot
sector viruses.
Note
If you carry out actions on running processes, the processes in question are terminated
before the actions are performed.
Actions of the Guard for detections made by the ProActiv component
(notification of suspicious actions of an application):
– Trusted program
The application continues to run. The program is added to the list of permitted
applications and is excluded from monitoring by the ProActiv component. When
adding to the list of permitted applications, the monitoring type is set to Content.
This means that the application is only excluded from monitoring by the ProActiv
component if the content remains unchanged (see
Configuration::Guard::ProActiv::Application filter: Permitted applications).
– Block program once
The application is blocked, i.e. the application is terminated. The actions of the
application continue to be monitored by the ProActiv component.
– Always block this program

Avira AntiVir Professional
6 Scanner
With the Scanner component, you can carry out targeted scans (on-demand scans) for
viruses and unwanted programs. The following options are available for scanning for
infected files:
– On-demand scan via context menu
The on-demand-scan via the context menu (right-hand mouse button - entry
Scan selected files with AntiVir) is recommended if, for example, you wish to
scan individual files and directories. Another advantage is that it is not necessary
to first start the Control Center for an on-demand scan via the context menu.
– On-demand scan via drag & drop
When a file or directory is dragged into the program window of the Control
Center, the Scanner scans the file or directory and all sub-directories it contains.
This procedure is recommended if you wish to scan individual files and
directories that you have saved, for example, on your desktop.
– On-demand scan via profiles
This procedure is recommended if you wish to regularly scan certain directories
and drives (e.g. your work directory or drives on which you regularly store new
files). You do not then need to select these directories and drives again for every
new scan, you simply select using the relevant profile.
– On-demand scan via the Scheduler
The Scheduler enables you to carry out time-controlled scans.
Special processes are required when scanning for rootkits, boot sector viruses, and when
scanning active processes. The following options are available:
– Scan for rootkits via the scan profile Scan for Rootkits and active malware
– Scan active processes via the scan profile Active processes
– Scan for boot sector viruses via the menu command Scan for boot sector
viruses in the Extras menu

7 Updates
The effectiveness of anti-virus software depends on how up-to-date the program is, in
particular the virus definition file and the scan engine. To carry out regular updates, the
Updater component is integrated into your AntiVir. The Updater ensures that your
AntiVir program is always up-to-date and able to deal with the new viruses that appear
every day. Updater updates the following components:
– Virus definition file:
The virus definition file contains the virus patterns of the harmful programs which
are used by your AntiVir program to scan for viruses and malware and repair
infected objects.
– Scan engine:
The scan engine contains the methods used by your AntiVir program to scan for
viruses and malware.
– Program files (product update):
Update packages for product updates make extra functions available to the
individual program components.
An update checks whether the virus definition file and scan engine are up-to-date and if
necessary implements an update. Depending on the settings in the configuration, the
Updater also carries out a product update or informs you of the product updates
available. After a product update, you may have to restart your computer system. If only
the virus definition file and scan engine are updated, the computer does not have to be
restarted.
Note
For security reasons, the Updater checks whether the Windows hosts file of your
computer was altered, whether the Update URL, for example, was manipulated by
malware and is diverting the Updater to unwanted download sites. If the Windows hosts
file has been manipulated, this is shown in the Updater report file.
An update is automatically performed in the following interval: 60 minutes. You can edit
or disable the automatic update through the configuration (Configuration::Update).
In the Control Center under Scheduler, you can create additional update jobs that are
performed by Updater at the specified intervals. You also have the option to start an
update manually:
– In the Control Center: in the Update menu and in the Status section
– via the context menu of the tray icon
Updates can be obtained from the Internet via a proprietary web server or via a web or
file server on an intranet which downloads the update files from the Internet and makes
them available to other computers on the network. This is useful if you want to update
AntiVir programs on more than one computer in a network. A download server on an
intranet can be used to ensure AntiVir programs are up-to-date on the protected
computers using a minimum of resources. To set up a functioning download server on an
intranet, you need a server that is compatible with the update structure of your AntiVir
program.
43
Page 49
Avira AntiVir Professional
Note
You can use AntiVir Internet Update Manager (file server or web server in Windows) as a
web server or file server in the intranet. AntiVir Internet Update Manager mirrors the
download servers of Avira AntiVir products and can be obtained from the Avira website
on the Internet.
http://www.avira.com
When a web server is used, the HTTP protocol is used for the download. When using a
file server, access to the update file is provided via the network. You can configure the
connection to the web server or file server in the Configuration under General :: Update.
The default configuration uses the existing Internet connection as the connection to the
Avira GmbH web servers.

8 Avira FireWall :: Overview
Avira FireWall monitors and regulates incoming and outgoing data traffic on your
computer system and protects you from a wide range of attacks and threats from the
Internet: Incoming or outgoing data traffic or listening to ports will be allowed or denied
based on security guidelines. You will receive a desktop notification if Avira FireWall
denies network activity and thus blocks network connections. The following options are
available for Avira FireWall settings:
– by setting a security level in the Control Center
You can define a security level in the Control Center. The low, medium and high
security levels each contain several complementary security rules based on packet
filters. These security rules are saved as predefined adapter rules in the
Configuration under FireWall::Adapter rules.
– by saving actions in the Network event window
When an application first tries to create a network or Internet connection, the
Network Event popup window appears. The Network Event window allows the user to
choose whether the network activity of the application is allowed or denied. If the
Save Action for this application option is enabled, the action is created as an
application rule and is saved in the configuration under FireWall::Application Rules.
Saving the actions in the Network event window gives you a set of rules for the
network activities of applications.
Note
For applications from trusted providers, network access is allowed by default unless an
adapter rule prohibits network access. You have the option of removing providers from
the list of trusted providers.
– by creating adapter and application rules in the Configuration
You can alter predefined adapter rules or create new adapter rules in the
Configuration. The security level of the FireWall is automatically set to the value
User if you add or change adapter rules.
Application rules allow you to define monitoring rules specified for applications:
You can use simple application rules to define whether all network activities of a
software application are to be denied or allowed or whether they are to be handled by
means of the Network Event popup window.
In the advanced configuration of the Application rules setting you can define different
packet filters for an application, which are executed as specified application rules.
Note
There are two different modes for application rules: Privileged and Filtered. For
application rules in filtered mode, the relevant adapter rules are prioritized, i.e. relevant
adapter rules are executed after the application rule. It is therefore possible that network
access may be denied due to a high security level or corresponding adapter rules. For
application rules in privileged mode, adapter rules are ignored. If applications are allowed
in privileged mode, the application is always granted network access.

Please check correct functioning of AntiVir MailGuard with the aid of the following
checklists if problems occur with AntiVir MailGuard.
Checklist
Check whether your mail client logs in on the server via Kerberos, APOP or RPA.
These verification methods are currently not
Check whether your mail client reports to the server through SSL (also often
called TSL – Transport Layer Security). AntiVir MailGuard does not support SSL and
therefore terminates any encrypted SSL connections. If you want to use encrypted SSL
connections without having them protected by MailGuard, you will have to use a port
that is not monitored by MailGuard for the connection. The ports monitored by
MailGuard can be configured in the configuration under MailGuard::Scan.
Is the AntiVir MailGuard service active? If necessary, enable the service: In the
taskbar, select "Start | Settings | Control Panel". Start the configuration panel "Services"
with a double-click (under Windows 2000 and Windows XP the services applet is located

There is no network connection available in a virtual machine (e.g. VMWare,
Virtual PC, ...) if Avira FireWall is installed on the host machine and the
security level of Avira FireWall is set to medium or high.
If Avira FireWall is installed on a computer on which a virtual machine (for example
VMWare, virtual PC, etc.) is also running, the firewall will block all network connections
for the virtual machine when the security level of the Avira FireWall is set to medium or
high. If the security level is set to low, the FireWall works as expected.

Page 54
FAQ, Tips
Reason: The virtual machine emulates a network card by means of software. This
emulation encapsulates the data packages of the guest system in special packages (UDP
packages) and routes them via the external gateway back to the host system. Avira
FireWall rejects these packages coming from outside, starting from security level
medium.
To avoid this behavior do the following:
Go to Control Center and select the section Online protection :: FireWall.
Click the Configuration link.
The Configuration dialog box is displayed. You are in the configuration section
Application rules.
Activate the Expert mode option.
Select the configuration section Adapter rules.
Click add rule.
Select UDP in the section Incoming rules.
Type the name of the rule in the Section Name of the rule .
Click OK.
Check if the rule is directly above the rule Deny all IP packets.
Warning
This rule is potentially dangerous because it will allow UDP packets without any filtering!
After working with the virtual machine change to your previous security level.
Virtual Private Network (VPN) Connection is blocked, if the security level of
Avira FireWall is set to medium or high.
Reason: This problem is caused by the last rule Deny all IP packets which discards all
packets that do not comply with any of the rules above it. The type of packages
dispatched by the VPN software (so-called GRE packets) do not fit into the other
categories and therefore they are filtered by this rule.
Replace the rule Deny all IP packets with two new rules which will deny the TCP and
UPD packets. In this way there is the possibility to allow packets of other protocols.
An email sent via a TSL connection has been blocked by MailGuard.
Reason: Transport Layer Security (TLS: encryption protocol for data transfers on the
Internet) is not supported by MailGuard at this time. The following options are available
for sending the email:
Use a different port from port 25, which is used by SMTP. This will bypass
monitoring by MailGuard.
Turn off the TSL encrypted connection and disable TSL support in your email
client.
Disable (temporarily) monitoring of outgoing emails by MailGuard in the
configuration under MailGuard::Scan.
Webchat is not operational: Chat messages are not displayed; data are being
loaded in the browser.

Avira AntiVir Professional
This phenomenon may occur during chats, which are based on the HTTP protocol with
'transfer-encoding= chunked’.
Reason: WebGuard checks the data sent completely for viruses and undesired programs
first of all, before the data are loaded into the web browser. During a data transfer with
‘transfer-encoding= chunked’, WebGuard cannot determine the message length or the
data volume.
Enter the configuration of the URL of the web chats as an exception (see
Configuration: WebGuard::Exceptions).

9.3.1 General
The Windows Security Center checks the status of a computer for important security
aspects.
If a problem is detected with one of these important points (e.g. an outdated anti-virus
program), the Security Center issues an alert and gives recommendations on how to
protect your computer better.
9.3.2 The Windows Security Center and your AntiVir program
FireWall
You may receive the following information from the Security Center with regard to your
firewall:
– FireWall ACTIVE / FireWall on
– FireWall INACTIVE / FireWall off
FAQ, Tips
FireWall ACTIVE / FireWall off
After installing your AntiVir program and turning off Windows Firewall, you will receive
the following message:
FireWall INACTIVE / FireWall off
You will receive the following message as soon as you disable the Avira FireWall:
Note
You can enable or disable the Avira FireWall via the Status tab in the Control Center.
Warning
If you turn the Avira FireWall off, your computer is no longer prevented by unauthorized
users from gaining access to it through a network or the Internet.

You may receive the following information from the Windows Security Center with
regard to your virus protection:
Virus protection NOT FOUND
Virus protection OUT OF DATE
Virus protection ON
Virus protection OFF
Virus protection NOT MONITORED
Virus protection NOT FOUND
This information of the Windows Security Center appears when the Windows Security
Center has not found any anti-virus software on your computer.
Note
Install your AntiVir program on your computer to protect it against viruses and other
unwanted programs!
Virus protection OUT OF DATE
If you have already installed Windows XP Service Pack 2 or Windows Vista and then
install your AntiVir program or you install Windows XP Service Pack 2 or Windows Vista
on a system on which your AntiVir program has already been installed, you will receive
the following message:
Note
In order for the Windows Security Center to recognize your AntiVir program as up-todate, an update must be performed after installation. Update your system by carrying
out an update.
54
Virus protection ON
After installation of your AntiVir program and a subsequent update, you will receive the
following message:
Page 60
FAQ, Tips
Your AntiVir program is now up-to-date and the AntiVir Guard is enabled.
Virus protection OFF
You receive the following message if you disable the AntiVir Guard or stop the Guard
service.
Note
You can enable or disabled AntiVir Guard in the Overview::Status section of the Control
Center. You can also see that the AntiVir Guard is enabled if the red umbrella in your
taskbar is open.
Virus protection NOT MONITORED
If you receive the following message from the Windows Security Center, you have
decided that you want to monitor your anti-virus software yourself.
Note
This function is not supported by Windows Vista.
Note
The Windows Security Center is supported by your AntiVir program. You can enable this
option at any time via the "Recommendations...." button.
Note
Even if you have installed Windows XP Service Pack 2 or Windows Vista, you still require
a virus protection solution. Although Windows XP Service Pack 2 monitors your antivirus software, it does not contain any anti-virus functions itself. Therefore you would
not be protected against viruses and other malware without an additional anti-virus
solution!

10 Viruses and more
10.1 Extended threat categories
Dialer (DIALER)
Certain services available in the Internet have to be paid for. They are invoiced in
Germany via dialers with 0190/0900 numbers (or via 09x0 numbers in Austria and
Switzerland; in Germany, the number is set to change to 09x0 in the medium term).
Once installed on the computer, these programs guarantee a connection via a suitable
premium rate number whose scale of charges can vary widely.
The marketing of online content via your telephone bill is legal and can be of advantage
to the user. Genuine dialers leave no room for doubt that they are used deliberately and
intentionally by the user. They are only installed on the user’s computer subject to the
user’s consent, which must be given via a completely unambiguous and clearly visible
labeling or request. The dial-up process of genuine dialers is clearly displayed. Moreover,
genuine dialers tell you the incurred costs exactly and unmistakably.
Unfortunately there are also dialers which install themselves on computers unnoticed,
by dubious means or even with deceptive intent. For example they replace the Internet
user’s default data communication link to the ISP (Internet Service Provider) and dial a
cost-incurring and often horrendously expensive 0190/0900 number every time a
connection is made. The affected user will probably not notice until his next phone bill
that an unwanted 0190/0900 dialer program on his computer has dialed a premium rate
number with every connection, resulting in dramatically increased costs.
We recommend that you ask your telephone provider to block this number range directly
for immediate protection against undesired dialers (0190/0900 dialers).
Your AntiVir program can detect the familiar dialers by default.
If the option Dialers is enabled with a check mark in the configuration under Extended
threat categories, you receive a corresponding alert if a dialer is detected. You can now
simply delete the potentially unwanted 0190/0900 dialer. However, if it is a wanted dialup program, you can declare it an exceptional file and this file is then no longer scanned
in future.
Games (GAMES)
There is a place for computer games - but it is not necessarily at work (except perhaps in
the lunch hour). Nevertheless, with the wealth of games downloadable from the
Internet, a fair bit of mine sweeping and Patience playing goes on among company
employees and civil servants. You can download a whole array of games via the Internet.
Email games have also become more popular: numerous variants are circulating, ranging
from simple chess to "fleet exercises" (including torpedo combats): The corresponding
moves are sent to partners via email programs, who answer them.
56
Page 62
Viruses and more
Studies have shown that the number of working hours devoted to computer games has
long reached economically significant proportions. It is therefore not surprising that
more and more companies are considering ways of banning computer games from
workplace computers.
Your AntiVir program recognizes computer games. If the Games option is enabled with
a check mark in the configuration under Threat categories, you receive a corresponding
alert if your AntiVir program detects a game. The game is now over in the truest sense of
the word, because you can simply delete it.
Jokes (JOKES)
Jokes are merely intended to give someone a fright or provide general amusement
without causing harm or reproducing. When a joke program is loaded, the computer will
usually start at some point to play a tune or display something unusual on the screen.
Examples of jokes are the washing machine in the disk drive (DRAIN.COM) or the screen
eater (BUGSRES.COM).
But beware! All symptoms of joke programs may also originate from a virus or Trojan. At
the very least users will get quite a shock or be thrown into such a panic that they
themselves may cause real damage.
Thanks to the extension of its scanning and identification routines, your AntiVir
program is able to detect joke programs and eliminate them as unwanted programs if
required. If the option Jokes is enabled with a check mark in the configuration under
Threat categories, a corresponding alert is issued if a joke program is detected.
Security Privacy Risk (SPR)
Software that may be able to compromise the security of your system, initiate unwanted
program activities, damage your privacy or spy on your user behavior and could
therefore be unwanted.
Your AntiVir program detects "Security Privacy Risk" software. If the option Security
Privacy Risk is enabled with a check mark in the configuration under Extended threat
categories, you receive a corresponding alert if your AntiVir program detects such
software.
Backdoor Clients (BDC)
In order to steal data or manipulate computers, a backdoor server program is smuggled
in unknown to the user. This program can be controlled by a third party using backdoor
control software (client) via the Internet or a network.
Your AntiVir program recognizes "Backdoor control software". If the Backdoor control
software (BDC) option is enabled with a check mark in the configuration under
Extended threat categories, you receive a corresponding alert if your AntiVir program
detects such software.
Adware/Spyware (ADSPY)
Software that displays advertising or software that sends the user’s personal data to a
third party, often without their knowledge or consent, and for this reason may be
unwanted.
57
Page 63
Avira AntiVir Professional
Your AntiVir program recognizes "Adware/Spyware". If the option Adware/Spyware
(ADSPY) is enabled with a check mark in the configuration under Extended threat
categories, you receive a corresponding alert if your AntiVir program detects adware or
spyware.
Unusual Runtime Packers (PCK)
Files that have been compressed with an unusual runtime packer and that can therefore
be classified as potentially suspicious.
Your AntiVir program recognizes "Unusual runtime packers". If the option Unusual
runtime packers is enabled with a check mark in the configuration under Extended
threat categories, you receive a corresponding alert if your AntiVir program detects such
packers.
Double Extension Files (HEUR-DBLEXT)
Executable files that hide their real file extension in a suspicious way. This camouflage
method is often used by malware.
Your AntiVir program recognizes "Double Extension Files". If the option Double
Extension files (HEUR-DBLEXT) is enabled with a check mark in the configuration
under Extended threat categories, you receive a corresponding alert if your AntiVir
program detects such files.
Phishing
Phishing, also known as brand spoofing is a clever form of data theft aimed at customers
or potential customers of Internet service providers, banks, online banking services,
registration authorities.
When submitting your email address on the Internet, filling in online forms, accessing
newsgroups or websites, your data can be stolen by "Internet crawling spiders" and then
used without your permission to commit fraud or other crimes.
Your AntiVir program recognizes "Phishing". If the option Phishing is enabled with a
check mark in the configuration under Extended threat categories, you receive a
corresponding alert if your AntiVir program detects such behavior.
Application (APPL)
The term APPL refers to an application which may involve a risk when used or is of
dubious origin.
Your AntiVir program recognizes "Application (APPL)". If the option Application
(APPL) is enabled with a check mark in the configuration under Extended threat
categories, you receive a corresponding alert if your AntiVir program detects such
behavior.
10.2 Viruses and other malware
Adware
58
Page 64
Viruses and more
Adware is software that presents banner ads or in pop-up windows through a bar that
appears on a computer screen. These advertisements usually cannot be removed and are
consequently always visible. The connection data allow many conclusions on the usage
behavior and are problematic in terms of data security.
Backdoors
A backdoor can gain access to a computer by bypassing the computer access security
mechanisms.
A program that is being executed in the background generally enables the attacker
almost unlimited rights. User's personal data can be spied with the backdoor's help.. But
are mainly used to install further computer viruses or worms on the relevant system.
Boot viruses
The boot or master boot sector of hard disks is mainly infected by boot sector viruses.
They overwrite important information necessary for the system execution. One of the
awkward consequences: the computer system cannot be loaded any more…
Bot-Net
A bot-net is defined as a remote network of PCs (on the Internet) that is composed of
bots that communicate with each other. A bot-net can comprise a collection of cracked
machines running programs (usually referred to as worms, Trojans) under a common
command and control infrastructure. Bot-nets serve various purposes, including denialof-service attacks etc., usually without the affected PC user's knowledge. The main
potential of bot-nets is that the networks can achieve grow to thousands of computers
and their total bandwidth exceeds most conventional Internet accesses.
Exploit
An exploit (security gap) is a computer program or script that takes advantage of a bug,
glitch or vulnerability leading to privilege escalation or denial of service on a computer
system. One form of exploitation for example is an attack from the Internet with the
help of manipulated data packages. Programs can be infiltrated in order to obtain higher
access.
Hoaxes
For several years, Internet and other network users have received alerts about viruses
that are purportedly spread via email. These alerts are spread via email with the request
that they should be sent to the highest possible number of colleagues and to other users,
in order to warn everyone against the "danger".
Honeypot
A honeypot is a service (program or server) installed in a network. Its function is to
monitor a network and log attacks. This service is unknown to the legitimate user because of this reason he is never addressed. If an attacker examines a network for the
weak points and uses the services which are offered by a honeypot, it is logged and an
alert is triggered.
59
Page 65
Avira AntiVir Professional
Macro viruses
Macroviruses are small programs that are written in the macro language of an
application (e.g. WordBasic under WinWord 6.0) and that can normally only spread
within documents of this application. Because of this, they are also called document
viruses. In order to be active, they need that the corresponding applications are activated
and that one of the infected macros has been executed. Unlike "normal" viruses, macro
viruses consequently do not attack executable files but they do attack the documents of
the corresponding host application.
Pharming
Pharming is a manipulation of the host file of web browsers to divert enquiries to
spoofed websites. This is a further development of classic phishing. Pharming fraudsters
operate their own large server farms on which fake websites are stored. Pharming has
established itself as an umbrella term for various types of DNS attacks. In the case of a
manipulation of the host file, a specific manipulation of a system is carried out with the
aid of a Trojan or virus. The result is that the system can now only access fake websites,
even if the correct web address is entered.
Phishing
Phishing means angling for personal details of the Internet user. Phishers generally send
their victims apparently official letters such as emails that are intended to induce them
to reveal confidential information to the culprits in good faith, in particular user names
and passwords or PINs and TANs of online banking accounts. With the stolen access
details, the phishers can assume the identities of the victims and carry out transactions
in their name. What is clear is that: banks and insurance companies never ask for credit
card numbers, PINs, TANs or other access details by email, SMS or telephone.
Polymorph viruses
Polymorph viruses are the real masters of disguise. They change their own programming
codes - and are therefore very hard to detect.
Program viruses
A computer virus is a program that is capable of attaching itself to other programs after
being executed and cause an infection. Viruses multiply themselves unlike logic bombs
and Trojans. In contrast to a worm, a virus always requires a program as host, where the
virus deposits its virulent code. The program execution of the host itself is not changed
as a rule.
60
Rootkit
A rootkit is a collection of software tools that are installed after a computer system has
been infiltrated to conceal logins of the infiltrator, hide processes and record data generally speaking: to make themselves invisible. They attempt to update already
installed spy programs and reinstall deleted spyware.
Script viruses and worms
Page 66
Viruses and more
Such viruses are extremely easy to program and they can spread - if the required
technology is on hand - within a few hours via email round the globe.
Script viruses and worms use one of the script languages, such as Javascript, VBScript
etc., to insert themselves in other, new scripts or to spread themselves by calling
operating system functions. This frequently happens via email or through the exchange
of files (documents).
A worm is a program that multiplies itself but that does not infect the host. Worms
cannot consequently form part of other program sequences. Worms are often the only
possibility to infiltrate any kind of damaging programs on systems with restrictive
security measures.
Spyware
Spyware are so called spy programs that intercept or take partial control of a computer's
operation without the user's informed consent. Spyware is designed to exploit infected
computers for commercial gain.
Trojan horses (short Trojans)
Trojans are pretty common nowadays. Trojans include programs that pretend to have a
particular function, but that show their real image after execution and carry out a
different function that, in most cases, is destructive. Trojan horses cannot multiply
themselves, which differentiates them from viruses and worms. Most of them have an
interesting name (SEX.EXE or STARTME.EXE) with the intention to induce the user to
start the Trojan. Immediately after execution they become active and can, for example,
format the hard disk. A dropper is a special form of Trojan that 'drops' viruses, i.e.
embeds viruses on the computer system.
Zombie
A zombie PC is a computer that is infected with malware programs and that enables
hackers to abuse computers via remote control for criminal purposes. On command, the
affected PC starts denial-of-service (DoS) attacks, for example, or sends spam and
phishing emails.

12 Reference: Configuration options
The configuration reference documents all available configuration options.
12.1 Scanner
The Scanner section of the Configuration is responsible for the configuration of the ondemand scan.
12.1.1 Scan
Here you define the basic behavior of the scan routine for an on-demand scan. If you
select certain directories to be scanned with an on-demand scan, depending on the
configuration the Scanner scans:
– with a certain scanning power (priority),
– also boot sectors and main memory,
– certain or all boot sectors and the main memory,
– all or selected files in the directory.
Files
The Scanner can use a filter to scan only those files with a certain extension (type).
All files
If this option is enabled, all files are scanned for viruses or unwanted programs,
irrespective of their content and file extension. The filter is not used.
Note
If All files is enabled, the button File extensions cannot be selected.
Smart Extensions
If this option is enabled, the selection of the files scanned for viruses or unwanted
programs is automatically chosen by the program. This means that your AntiVir program
decides whether the files are scanned or not based on their content. This procedure is
somewhat slower than Use file extension list, but more secure, since not only on the
basis of the file extension is scanned. This option is enabled as the default setting and is
recommended.
Note
If Smart Extensions is enabled, the button File extensions cannot be selected.
Use file extension list
If this option is enabled, only files with a specified extension are scanned. All file types
that may contain viruses and unwanted programs are preset. The list can be edited
manually via the button "
File extension".
64
Page 70
Reference: Configuration options
Note
If this option is enabled and you have deleted all entries from the list with file
extensions, this is indicated with the text "No file extensions" under the button File
extensions.
File extensions
With the aid of this button, a dialog box is opened in which all file extensions are
displayed that are scanned in "Use file extension list" mode. Default entries are set for
the extensions, but entries can be added or deleted.
Note
Please note that the default list may vary from version to version.
Additional settings
Scan boot sectors of selected drives
If this option is enabled, the Scanner scans the boot sectors of the drives selected for the
on-demand scan. This option is enabled as the default setting.
Scan master boot sectors
If this option is enabled, the Scanner scans the master boot sectors of the hard disk(s)
used in the system.
Ignore offline files
If this option is enabled, the direct scan ignores so-called offline files completely during a
scan. This means that these files are not scanned for viruses and unwanted programs.
Offline files are files that were physically moved by a so-called Hierarchical Storage
Management System (HSMS) from the hard disk onto a tape, for example. This option is
enabled as the default setting.
Integrity checking of system files
When this option is enabled, the most important Windows system files are subjected to
a particularly secure check for changes by malware during every on-demand scan. If an
amended file is detected, this is reported as suspect. This function uses a lot of computer
capacity. That is why the option is disabled as the default setting.
Important
This option is only available with Windows Vista and higher. The option is not available
if you are managing the AntiVir program under SMC.
Note
This option should not be used if you are using third-party tools that modify system files
and adapt the boot or start screen to your own requirements. Examples of such tools are
skinpacks, TuneUp utilities or Vista Customization.
Optimized scan
When the option is enabled, the processor capacity is optimally utilized during a Scanner
scan. For performance reasons, an optimized scan is only logged on standard level.
Note
This option is only available on multi-processor systems. If your AntiVir program is
managed with SMC, the option is always displayed and can be enabled: If the managed
system does not have more than one processor, the Scanner option is not used.
Follow symbolic links
65
Page 71
Avira AntiVir Professional
If this option is enabled, Scanner performs a scan that follows all symbolic links in the
scan profile or selected directory and scans the linked files for viruses and malware. This
option is not supported by Windows 2000 and has been deactivated.
Important
The option does not include any shortcuts, but refers exclusively to symbolic links
(generated by mklink.exe) or Junction Points (generated by junction.exe) that are
transparent in the file system.
Search for Rootkits before scan
If this option is enabled and a scan is started, the Scanner scans the Windows system
directory for active rootkits in a so-called shortcut. This process does not scan your
computer for active rootkits as comprehensively as the scan profile "Scan for rootkits",
but it is significantly quicker to perform.
Important
The rootkit scan is not available for Windows XP 64 bit !
Scan Registry
If this option is enabled, the Registry is scanned for references to malware.
Do not scan files and paths on network drives
If this option is enabled, network drives connected to the computer are excluded from
the on-demand scan. This option is recommended when the servers or other
workstations are themselves protected with anti-virus software. This option is disabled
as the default setting.
Scan process
Allow stopping the Scanner
If this option is enabled, the scan for viruses or unwanted programs can be terminated at
any time with the button "Stop" in the "Luke Filewalker" window. If you have disabled
this setting, the
Stop button in the "Luke Filewalker" window has a gray background.
Premature ending of a scan process is thus not possible! This option is enabled as the
default setting.
Scanner priority
With the on-demand scan, the Scanner distinguishes between priority levels. This is only
effective if several processes are running simultaneously on the workstation. The
selection affects the scanning speed.
Low
The Scanner is only allocated processor time by the operating system if no other process
requires computation time, i.e. as long as only the Scanner is running, the speed is
maximum. All in all, work with other programs is optimal: The computer responds more
quickly if other programs require computation time while the Scanner continues running
in the background. This option is enabled as the default setting and is recommended.
Medium
The Scanner is executed with normal priority. All processes are allocated the same
amount of processor time by the operating system. Under certain circumstances, work
with other applications may be affected.
High
The Scanner has the highest priority. Simultaneous work with other applications is
almost impossible. However, the Scanner completes its scan at maximum speed.
66
Page 72
12.1.1.1. Action on detection
Action on detection
You can define the actions to be performed by Scanner when a virus or unwanted
program is detected.
Interactive
If this option is enabled, the results of the Scanner scan are displayed in a dialog box.
When carrying out a scan with the Scanner, you will receive an alert with a list of the
affected files at the end of the scan. You can use the content-sensitive menu to select an
action to be executed for the various infected files. You can execute the standard actions
for all infected files or cancel the Scanner.
Note
In the Scanner dialog, the action 'Move to quarantine' is displayed as the default action.
Permitted actions
In this box actions can be specified, which can be selected in individual or expert
notification mode in case of a virus detection. You must activate the corresponding
options for this.
Repair
The Scanner repairs the infected file if possible.
rename
The Scanner renames the file. Direct access to these files (e.g. with double-click) is
therefore no longer possible. The file can be repaired at a later time and renamed again.
Quarantine
The Scanner moves the file to Quarantine. The file can be recovered from quarantine
manager if it has an informative value or - if necessary - sent to the Avira Malware
Research Center. Depending on the file, further selection options are available in the
quarantine manager.
delete
The file will be deleted. This process is much faster than "overwrite and delete".
Ignore
The file is to be ignored.
overwrite and delete
The Scanner overwrites the file with a default pattern and then deletes it. It cannot be
restored.
Default
The button is used to define a default action by the Scanner to handle the files
encountered. Highlight an action and click the "Default" button. Only the selected
default action for the relevant files can be executed in combined notification mode. The
selected default action for the relevant files is preselected in individual and expert
notification mode.
Reference: Configuration options
Note
The action repair cannot be selected as the default action.
Note
If you have selected Delete or Overwrite and Delete as the default action and wish to set
the notification mode to combined, please note the following: In the case of heuristic
hits, the affected files are not deleted, but are instead moved to quarantine.

Automatic
If this option is enabled, no dialog box in case of a virus detection appears. The Scanner
reacts according to the settings you predefine in this section as primary and secondary
action.
Backup to quarantine
If this option is enabled, the Scanner creates a backup copy before carrying out the
requested primary or secondary action. The back-up copy is saved in Quarantine, where
the file can be restored if it is of informative value. You can also send the backup copy to
the Avira Malware Research Center for further investigation.
Display detection alerts
If this option is activated, then for each detection of a virus or unwanted program an
alert appears showing the actions being executed.
Primary action
Primary action is the action performed when the Scanner finds a virus or an unwanted
program. If the option "repair" is selected but the affected file cannot be repaired, the
action selected under "Secondary action" is performed.
Note
The option Secondary action can only be selected if the setting repair was selected
under Primary action.
Repair
If this option is enabled, the Scanner repairs affected files automatically. If the Scanner
cannot repair an affected file, it carries out the action selected under Secondary action.
Note
An automatic repair is recommended, but means that the Scanner modifies files on the
workstation.
delete
If this option is enabled, the file is deleted. This process is much faster than "overwrite
and delete".
overwrite and delete
If this option is enabled, the Scanner overwrites the file with a default pattern and then
deletes it. It cannot be restored.
rename
If this option is enabled, the Scanner renames the file. Direct access to these files (e.g.
with double-click) is therefore no longer possible. Files can later be repaired and given
their original names again.
Ignore
If this option is enabled, access to the file is allowed and the file is left as it is.
68
Warning
The affected file remains active on your workstation! It may cause serious damage on
your workstation!
Quarantine
If this option is enabled, the Scanner moves the file to the quarantine. These files can
later be repaired or - if necessary - sent to the Avira Malware Research Center.
Secondary action
Page 74
Reference: Configuration options
The option "Secondary action" can only be selected if the setting repair was selected
under "Primary action". With this option it can now be decided what is to be done with
the affected file if it cannot be repaired.
delete
If this option is enabled, the file is deleted. This process is much faster than "overwrite
and delete".
overwrite and delete
If this option is enabled, the Scanner overwrites the file with a default pattern and then
deletes (wipes) it. It cannot be restored.
rename
If this option is enabled, the Scanner renames the file. Direct access to these files (e.g.
with double-click) is therefore no longer possible. Files can later be repaired and given
their original names again.
Ignore
If this option is enabled, access to the file is allowed and the file is left as it is.
Warning
The affected file remains active on your workstation! It may cause serious damage on
your workstation!
Quarantine
If this option is enabled, the Scanner moves the file to Quarantine. These files can later
be repaired or - if necessary - sent to the Avira Malware Research Center.
Note
If you have selected Delete or Overwrite and Delete as the primary or secondary
action, you should note the following: In the case of heuristic hits, the affected files are
not deleted, but are instead moved to quarantine.
12.1.1.2. Further actions
Launch program following detection
After the on-demand scan, the Scanner can open a file of your choice (for example a
program) if at least one virus or unwanted program has been detected, for example an
email program, so that you can inform other users or the administrator.
Note
For security reasons it is only possible to start a program after a detection when a user is
logged on the computer. The file is then opened with the rights that apply to the logged
on user. If no user is logged on, this option is not performed.
Program name
In this input box you can enter the name and the relevant path of the program that the
Scanner should start after a detection.
This button opens a window in which you can select the desired program with the aid of
the file selection dialog.
Arguments
69
Page 75
Avira AntiVir Professional
In this input box you can enter command line parameters for the program to be started
if necessary.
Event log
Use event log
If this option is enabled, an event report with the results of the scan is transferred to the
Windows Event Log after a Scanner scan has been completed. The events can be called
up in the Windows Event Viewer. The option is disabled as the default setting.
When scanning archives, the Scanner uses a recursive scan: Archives in archives are also
unpacked and scanned for viruses and unwanted programs. The files are scanned,
decompressed and scanned again.
Scan archives
If this option is enabled, the selected archives in the archive list are scanned. This option
is enabled as the default setting.
All archive types
If this option is enabled, all archive types in the archive list are selected and scanned.
Smart Extensions
If this option is enabled, the Scanner detects whether a file is a packed file format
(archive), even if the file extension differs from the usual extensions, and scans the
archive. However every file must be opened for this, which reduces the scanning speed.
Example: If a *.zip archive has the file extension *.xyz, the Scanner also unpacks this
archive and scans it. This option is enabled as the default setting.
Note
Only those archive types marked in the archive list are supported.
Recursion depth
Unpacking and scanning recursive archives can require a great deal of computer time and
resources. If this option is enabled, you limit the depth of the scan in multi-packed
archives to a certain number of packing levels (maximum recursion depth). This saves
time and computer resources.
Note
In order to find a virus or an unwanted program in an archive, the Scanner must scan up
to the recursion level in which the virus or the unwanted program is located.
Maximum recursion depth
In order to enter the maximum recursion depth, the option Limit recursion depth must
be enabled.
You can either enter the requested recursion depth directly or by means of the right
arrow key on the entry field. The permitted values are 1 to 99. The standard value is 20
which is recommended.
Default values
The button restores the pre-defined values for scanning archives.
70
Archives
Page 76
In this display area you can set which archives the Scanner should scan. For this, you
must select the relevant entries.
12.1.1.3. Exceptions
File objects to be omitted for the Scanner
The list in this window contains files and paths that should not be included by the
Scanner in the scan for viruses or unwanted programs.
Please enter as few exceptions as possible here and really only files that, for whatever
reason, should not be included in a normal scan. We recommend that you always scan
these files for viruses or unwanted programs before they are included in this list!
Note
The entries in the list must not result in more than 6000 characters in total.
Warning
These files are not included in a scan!
Note
The files included in this list are recorded in the report file. Please check the report file
from time to time for unscanned files, as perhaps the reason you excluded a file here no
longer exists. In this case you should remove the name of this file from this list again.
Reference: Configuration options
Input box
In this input box you can enter the name of the file object that is not included in the ondemand scan. No file object is entered as the default setting.
The button opens a window in which you can select the required file or the required
path.
When you have entered a file name with its complete path, only this file is not scanned
for infection. If you have entered a file name without a path, all files with this name
(irrespective of the path or drive) are not scanned.
Add
With this button, you can add the file object entered in the input box to the display
window.
Delete
The button deletes a selected entry from the list. This button is inactive if no entry is
selected.
Note
If you add a complete partition to the list of the file objects, only those files that are
saved directly under the partition will be excluded from the scan, which does not apply
to files in sub-directories on the corresponding partition:
Example: File object to be skipped: D:\ = D:\file.txt will be excluded from the
scan of the Scanner, D:\folder\file.txt will not be excluded from the scan.
Note
If you are managing the AntiVir program in SMC, you can use variables in the path
details for file exceptions. You can find a list of variables you can use under Variables:
Guard und Scanner Exceptions.

12.1.1.4. Heuristics
This configuration section contains the settings for the heuristic of the scan engine.
AntiVir products contain very powerful heuristics that can proactively uncover unknown
malware, i.e. before a special virus signature to combat the damaging element has been
created and before a virus guard update has been sent. Virus detection involves an
extensive analysis and investigation of the affected codes for functions typical of
malware. If the code being scanned exhibits these characteristic features, it is reported as
being suspicious. This does not necessarily mean that the code is in fact malware. False
positives do sometimes occur. The decision on how to handle affected code is to be made
by the user, e.g. based on his or her knowledge of whether the source of the code is
trustworthy or not.
Macrovirus heuristics
Macrovirus heuristics
Your AntiVir product contains a highly powerful macrovirus heuristic. If this option is
enabled, all macros in the relevant document are deleted in the event of a repair,
alternatively suspect documents are only reported, i.e. you receive an alert. This option is
enabled as the default setting and is recommended.
Advanced Heuristic Analysis and Detection (AHeAD)
enable AHeAD
Your AntiVir program contains a very powerful heuristic in the form of AntiVir AHeAD
technology, which can also detect unknown (new) malware. If this option is enabled, you
can define how "aggressive" this heuristic should be. This option is enabled as the default
setting.
Low detection level
If this option is enabled, slightly less unknown malware is detected, the risk of false
alerts is low in this case.
Medium detection level
This option is enabled as the default setting if you have selected the use of this heuristic.
High detection level
If this option is enabled, significantly more unknown malware is detected, but there are
also likely to be false positives.
12.1.2 Report
The Scanner has a comprehensive reporting function. You thus obtain precise
information on the results of an on-demand scan. The report file contains all entries of
the system as well as alerts and messages of the on-demand scan.
72
Note
To enable you to establish what actions the Scanner has performed when viruses or
unwanted programs have been detected, a report file should always be created.
Reporting
Page 78
Reference: Configuration options
Off
If this option is enabled, the Scanner does not report the actions and results of the ondemand scan.
Default
When this option is activated, the Scanner logs the names of the files concerned with
their path. In addition, the configuration for the current scan, version information and
information on the licensee is written in the report file.
Advanced
When this option is activated, the Scanner logs alerts and tips in addition to the default
information.
Complete
When this option is activated, the Scanner also logs all scanned files. In addition, all files
involved as well as alerts and tips are included in the report file.
Note
If you have to send us a report file at any time (for troubleshooting), please create this
report file in this mode.
12.2 Guard
The Guard section of the configuration is responsible for the configuration of the onaccess scan.
12.2.1 Scan
You will normally want to monitor your system constantly. To this end, use the Guard (=
on-access Scanner). You can thus scan all files that are copied or opened on the computer
"on the fly", for viruses and unwanted programs.
Scan mode
Here the time for scanning of a file is defined.
Scan when reading
If this option is enabled, the Guard scans the files before they are read or executed by the
application or the operating system.
Scan when writing
If this option is enabled, the Guard scans a file when writing. You can only access the file
again after this process has been completed.
Scan when reading and writing
If this option is enabled, the Guard scans files before opening, reading and executing and
after writing. This option is enabled as the default setting and is recommended.
Files
The Guard can use a filter to scan only those files with a certain extension (type).
All files
73
Page 79
Avira AntiVir Professional
If this option is enabled, all files are scanned for viruses or unwanted programs,
irrespective of their content and their file extension.
Note
If All files is enabled, the File extensions button cannot be selected.
Smart Extensions
If this option is enabled, the selection of the files scanned for viruses or unwanted
programs is automatically chosen by the program. This means that the program decides
whether the files are scanned or not based on their content. This procedure is somewhat
slower than Use file extension list, but more secure, since not only on the basis of the file
extension is scanned.
Note
If Smart Extensions is enabled, the File extensions button cannot be selected.
Use file extension list
If this option is enabled, only files with a specified extension are scanned. All file types
that may contain viruses and unwanted programs are preset. The list can be edited
manually via the "
and is recommended.
File extensions" button. This option is enabled as the default setting
Note
If this option is enabled and you have deleted all entries from the list with file
extensions, this is indicated with the text "No file extensions" under the File extensions
button.
File extensions
With the aid of this button, a dialog box is opened in which all file extensions are
displayed that are scanned in "Use file extension list" mode. Default entries are set for
the extensions, but entries can be added or deleted.
Note
Please note that the file extension list may vary from version to version.
Archives
Scan archives
If this option is enabled, then archives will be scanned. Compressed files are scanned,
then decompressed and scanned again. This option is deactivated by default. The archive
scan is restricted by the recursion depth, the number of files to be scanned and the
archive size. You can set the maximum recursion depth, the number of files to be
scanned and the maximum archive size.
Note
This option is deactivated by default, since the process puts heavy demands on the
computer's performance. It is generally recommended that archives be checked using an
on-demand scan.
74
Maximum recursion depth
When scanning archives, the Guard uses a recursive scan: Archives in archives are also
unpacked and scanned for viruses and unwanted programs. You can define the recursion
depth. The default value for the recursion depth is 1 and is recommended: all archives
that are directly located in the main archive are scanned.
Maximum number of files
Page 80
Reference: Configuration options
When scanning archives, you can restrict the scan to a maximum number of files in the
archive. The default value for the maximum number of files to be scanned is 10 and is
recommended.
Maximum size (KB)
When scanning archives, you can restrict the scan to a maximum archive size to be
unpacked. The standard value of 1000 KB is recommended.
Drives
Network drives
If this option is enabled, files on network drives (mapped drives) such as server volumes,
peer drives etc., are scanned.
Note
In order not to reduce the performance of your computer too much, the option Network
drives should only be enabled in exceptional cases.
Warning
If this option is disabled, the network drives are not monitored. You are no longer
protected against viruses or unwanted programs!
Note
When files are executed on network drives, they are scanned by the Guard irrespective of
the setting for the Network Drives option. In some cases files on network drives are
scanned while being opened, even though the Network Drives option is disabled. Reason:
These files are accessed with ‘Execute File’ rights. If you want to exclude these files or
even executed files on network drives from scanning by the Guard, enter the files in the
list of file objects to be excluded (see: Guard::Scan::Exceptions).
Enable caching
If this option is enabled, monitored files on network drives will be made available in the
Guard's cache. Monitoring of network drives without the caching function is more
secure, but does not perform as well as the monitoring of network drives with caching.
12.2.1.1. Action on detection
Action on detection
You can define the actions to be performed by Guard when a virus or unwanted program
is detected.
Interactive
If this option is enabled, a desktop notification appears when Guard detects a virus or
unwanted program. You have the option of removing the detected malware or accessing
other possible virus treatment actions via the 'Details' button. The actions are displayed
in a dialog box. The actions will be displayed in a dialog box. This option is enabled as the
default setting.
Permitted actions
In this display box you can specify the virus management actions that should be available
as further actions in the dialog box. You must activate the corresponding options for
this.
repair
75
Page 81
Avira AntiVir Professional
Guard repairs the infected file if possible.
rename
Guard renames the file. Direct access to these files (e.g. with double-click) is therefore no
longer possible. The file can be repaired at a later time and renamed again.
Quarantine
Guard moves the file to Quarantine. The file can be recovered from quarantine manager
if it has an informative value or - if necessary - sent to the Avira Malware Research
Center. Depending on the file, further selection options are available in the quarantine
manager .
delete
The file will be deleted. This process is much faster than "overwrite and delete".
Ignore
Access to the file is permitted and the file is ignored.
overwrite and delete
Guard overwrites the file with a default pattern before deleting it. It cannot be restored.
Default
This button allows you to select an action that is activated in the dialog box by default
when a virus is detected. Select the action that should be activated by default and click
on the "Default" button.
Note
The action repair cannot be selected as the default action.
Click here for more information.
Automatic
If this option is enabled, no dialog box in case of a virus detection appears. Guard reacts
according to the settings you predefine in this section as primary and secondary action.
Backup to quarantine
If this option is enabled, the Guard creates a backup copy before carrying out the
requested primary or secondary action. The backup copy is saved in quarantine. It can be
restored via the quarantine manager if it is of informative value. You can also send the
backup copy to the Avira Malware Research Center. Depending on the object, more
selection options are available in the quarantine manager .
Display detection alerts
If this option is enabled, then for each detection of a virus or unwanted program an alert
appears.
Primary action
Primary action is the action performed when the Guard finds a virus or an unwanted
program. If the "repair" option is selected but the affected file cannot be repaired, the
action selected under "Secondary action" is performed.
Note
The Secondary action option can only be selected if the repair setting was selected under
Primary action.
76
repair
If this option is enabled, the Guard repairs affected files automatically. If the Guard
cannot repair an affected file, it carries out the action selected under Secondary action.
Page 82
Reference: Configuration options
Note
An automatic repair is recommended, but means that the Guard modifies files on the
workstation.
delete
If this option is enabled, the file is deleted. This process is much faster than "overwrite
and delete".
overwrite and delete
If this option is enabled, the Guard overwrites the file with a default pattern and then
deletes it. It cannot be restored.

If this option is enabled, the Guard renames the file. Direct access to these files (e.g. with
double-click) is therefore no longer possible. Files can later be repaired and given their
original names again.
Ignore
If this option is enabled, access to the file is allowed and the file is left as it is.
Warning
The affected file remains active on your workstation! It may cause serious damage on
your workstation!
Deny access
If this option is enabled, the Guard only enters the detection in the report file if the
report function is enabled. In addition, the Guard writes an entry in the Event log, if this
option is enabled.
Quarantine
If this option is enabled, the Guard moves the file to Quarantine. The files in this
directory can later be repaired or - if necessary - sent to the Avira Malware Research
Center.
Secondary action
The option "Secondary action" can only be selected if the "Repair" option was selected
under "Primary action". With this option it can now be decided what is to be done with
the affected file if it cannot be repaired.

If this option is enabled, the Guard moves the file to Quarantine. The files can later be
repaired or - if necessary - sent to the Avira Malware Research Center.
Note
If you have selected Delete or Overwrite and Delete as the primary or secondary
action, please note the following: In the case of heuristic hits, the affected files are not
deleted, but are instead moved to quarantine.
12.2.1.2. Further actions
Notifications
Event log
Use event log
If this option is enabled, an entry is added to the Windows event log for every detection.
The events can be called up in the Windows event viewer. This option is enabled as the
default setting.
Autostart
Block autostart function
When this option is enabled, the execution of the Windows Autostart function is blocked
on all connected drives, including USB sticks, CD and DVD drives and network drives.
With the Windows Autostart function, files on data media or network drives are read
immediately on loading or connection, and files can therefore be started and copied
automatically. This functionality carries with it a high security risk, however, as malware
and unwanted programs can be installed with the automatic start. The Autostart
function is especially critical for USB sticks as data on a stick can be changed at any time.
Exclude CDs and DVDs
When this option is enabled, the Autostart function is permitted on CD and DVD drives.
Warning
Only disable the Autostart function for CD and DVD drives if you are sure you are only
using trusted data media.
78
Page 84
12.2.1.3. Exceptions
With these options you can configure exception objects for the Guard (on-access scan).
The relevant objects are then not included in the on-access scan. The Guard can ignore
file accesses to these objects during the on-access scan via the list of processes to be
omitted. This is useful, for example, with databases or backup solutions.
Please note the following when specifying processes and file objects to be omitted: The
list is processed from top to bottom. The longer the list is, the more processor time is
required for processing the list for each access. Therefore, keep the list as short as
possible.
Processes to be omitted by the Guard
All file accesses of processes in this list are excluded from monitoring by Guard.
Input box
In this field, enter the name of the process that is to be ignored by the real-time scan. No
process is entered as the default setting.
Note
You can enter up to 128 processes.
Reference: Configuration options
Note
When entering the process, Unicode symbols are accepted. You can therefore enter
process or directory names containing special symbols.
Note
You have the option of excluding processes from monitoring by the Guard without full
path details.
application.exe
This however only applies to processes where the executable files are located on hard
disk drives.
Full path details are required for processes where the executable files are located on
connected drives, e.g. network drives. Please note the general information on the
notation of Exceptions on connected network drives.
Do not specify any exceptions for processes where the executable files are located on
dynamic drives. Dynamic drives are used for removable disks, such as CDs, DVDs or USB
sticks.
Note
Drive information must be entered as follows: [Drive letter]:\
The colon symbol (:) is only used to specify drives.
Note
When specifying the process, you can use the wildcards* (any number of characters) and
?? (a single character).
C:\Program Files\Application\application.exe
C:\Program Files\Application\applicatio?.exe
C:\Program Files\Application\applic*.exe
C:\Program Files\Application\*.exe
To avoid the process being excluded globally from monitoring by Guard, specifications
exclusively comprising the following characters are invalid: * (asterisk), ? (question
mark), / (forward slash), \ (backslash), . (dot), : (colon).
Note
The specified path and file name of the process should contain a maximum of 255
characters. The entries in the list must not result in more than 6000 characters in total.
79
Page 85
Avira AntiVir Professional
Warning
Please note that all file accesses by processes recorded in the list are excluded from the
scan for viruses and unwanted programs! The Windows Explorer and the operating
system itself cannot be excluded. A corresponding entry in the list is ignored.
The button opens a window in which you can select an executable file.
Processes
The "Processes" button opens the" Process selection" window in which the running
processes are displayed.
Add
With this button, you can add the process entered in the input box to the display
window.
Delete
With this button you can delete a selected process from the display window.
File objects to be omitted by the Guard
All file accesses to objects in this list are excluded from monitoring by the Guard.
Input box
In this box you can enter the name of the file object that is not included in the on-access
scan. No file object is entered as the default setting.
Note
When specifying file objects to be omitted, you can use the wildcards* (any number of
characters) and ?? (a single character): Individual file extensions can also be excluded
(including wildcards):
C:\Directory\*.mdb
*.mdb
*.md?
*.xls*
C:\Directory\*.log
Note
Directory names must end with a backslash \, otherwise a file name is assumed.
Note
The entries in the list must have no more than 6000 characters in total.
Note
If a directory is excluded, all its sub-directories are automatically also excluded.
Note
For each drive you can specify a maximum of 20 exceptions by entering the complete
path (starting with the drive letter).
For example: C:\Program Files\Application\Name.log
The maximum number of exceptions without a complete path is 64.
For example: *.log
\computer1\C\directory1
80
Page 86
Reference: Configuration options
Note
In case of dynamic drives that are mounted as a directory on another drive, the alias of
the operating system for the integrated drive in the list of the exceptions has to be used:
e.g. \Device\HarddiskDmVolumes\PhysicalDmVolumes\BlockVolume1\
If you use the mount point itself, for example, C:\DynDrive, the dynamic drive will be
scanned nonetheless. You can determine the alias of the operating system to be used
from the Guard report file.
The button opens a window in which you can select the file object to be excluded.
Add
With this button, you can add the file object entered in the input box to the display
window.
Delete
With this button you can delete a selected file object from the display window.
Please note the further information when specifying exceptions:
Note
In order to also exclude objects when they are accessed with short DOS file names (DOS
name convention 8.3), the relevant short file name must also be entered in the list.
Note
A file name that contains wildcards may not be terminated with a backslash.
For example:
C:\Program Files\Application\applic*.exe\
This entry is not valid and not treated as an exception!
Note
Please note the following with regard to exceptions on connected network drives: If you
use the drive letter of the connected network drive, the files and folders specified are
NOT excluded from the Guard scan. If the UNC path in the list of exceptions differs from
the UNC path used to connect to the network drive (IP address specification in the list of
exceptions – specification of computer name for connection to network drive), the
specified folders and files are NOT excluded by the Guard scan. Locate the relevant UNC
path in the Guard report file:
\\<Computer name>\<Enable>\ - OR - \\<IP address>\<Enable>\
Note
You can locate the path Guard uses to scan for infected files in the Guard report file.
Indicate exactly the same path in the list of exceptions. Proceed as follows: Set the
protocol function of the Guard to Complete in the configuration under Guard::Report.
Now access the files, folders, mounted drives or connected network drives with the
activated Guard. You can now read the path to be used from the Guard report file. The
report file can be accessed in the Control Center under Local protection::Guard.
Note
If you are managing the AntiVir program in SMC, you can use variables in the path
details for process and file exceptions. You can find a list of variables you can use under
Variables: Guard and Scanner Exceptions.
Examples for processes to be excluded:
– application.exe
81
Page 87
Avira AntiVir Professional
The application.exe process is excluded from the Guard scan, irrespective of which
hard disk drive it is located on and which directory it is in.
– C:\Program Files1\Application.exe
The process for the file application.exe, which is located under the path C:\Program
Files1, is excluded from the Guard scan.
– C:\Program Files1\*.exe
All processes for executable files located under the path C:\Program Files1 are
excluded from the Guard scan.
Examples for files to be excluded:
– *.mdb
All files with the extension 'mdb’ are excluded from the Guard scan
– *.xls*
All files with a file extension beginning 'xls’ are excluded from the Guard scan, e.g.
files with the extensions .xls and .xlsx.
– C:\Directory\*.log
All log files with the extension 'log’, located under the path C:\Directory, are
excluded from the Guard scan.
– \\Computer name\Shared1\
All files are excluded from the Guard scan accessed via a connection '\\Computer
name1\Shared1'. This is generally a connected network drive which accesses another
computer with a shared folder via the computer name ‘Computer name1’ and the
shared name 'Shared1’.
– \\1.0.0.0\Shared1\*.mdb
All files with the extension ‘mdb’ are excluded from the Guard scan accessed via a
connection '\\1.0.0.0\Shared1'. This is generally a connected network drive which
accesses another computer with a shared folder via the IP address '1.0.0.0' and the
shared name 'Shared1’.

This configuration section contains the settings for the heuristic of the scan engine.
AntiVir products contain very powerful heuristics that can proactively uncover unknown
malware, i.e. before a special virus signature to combat the damaging element has been
created and before a virus guard update has been sent. Virus detection involves an
extensive analysis and investigation of the affected codes for functions typical of
malware. If the code being scanned exhibits these characteristic features, it is reported as
being suspicious. This does not necessarily mean that the code is in fact malware. False
positives do sometimes occur. The decision on how to handle affected code is to be made
by the user, e.g. based on his or her knowledge of whether the source of the code is
trustworthy or not.

Reference: Configuration options
Macrovirus heuristics
Your AntiVir product contains a highly powerful macrovirus heuristic. If this option is
enabled, all macros in the relevant document are deleted in the event of a repair,
alternatively suspect documents are only reported, i.e. you receive an alert. This option is
enabled as the default setting and is recommended.
Advanced Heuristic Analysis and Detection (AHeAD)
enable AHeAD
Your AntiVir program contains a very powerful heuristic in the form of AntiVir AHeAD
technology, which can also detect unknown (new) malware. If this option is enabled, you
can define how "aggressive" this heuristic should be. This option is enabled as the default
setting.
Low detection level
If this option is enabled, slightly less unknown malware is detected, the risk of false
alerts is low in this case.
Medium detection level
This option is enabled as the default setting if you have selected the use of this heuristic.
High detection level
If this option is enabled, significantly more unknown malware is detected, but there are
also likely to be false positives.
12.2.2 ProActiv
Avira AntiVir ProActiv protects you from new and unknown threats for which there are
not yet any virus definitions or heuristics available. ProActiv technology is integrated
into the Guard component and observes and analyzes the program actions performed.
The behavior of the program is checked against typical malware action patterns: Type of
action and action sequences. If a program exhibits behavior typical of malware, this is
treated as a virus detection : You have the option of blocking the program or ignoring
the notification and continuing to use the program. You can classify the program as
trusted and add it to the application filter for permitted programs. You have the option
of adding the program to the application filter for blocked programs using the Always
block command.
The ProActiv component uses rule sets developed by the Avira Malware Research Center
to identify suspicious behavior. The rule sets are supplied by Avira GmbH databases.
Avira AntiVir ProActiv sends information on any suspicious programs detected to the
Avira databases for logging. You have the option of disabling data transmission to the
Avira databases
Note
ProActiv technology is not yet available for 64 bit systems! Windows 2000 does not
support ProActiv components.
General
Enabling Avira AntiVir ProActiv

Avira AntiVir Professional
If this option is enabled, programs on your computer system are monitored and checked
for suspicious actions. You will receive a message if typical malware behavior is detected.
You can block the program or select "Ignore" to continue to use the program. The
monitoring process excludes: Programs classified as trusted, trusted and signed
programs included by default in the permitted applications filter, and all programs which
you have added to the application filter for permitted programs.
Participating in the AntiVir ProActiv Community enhances your computer’s security.
If this option is enabled, Avira AntiVir ProActiv sends data on suspicious programs and,
in certain cases, suspicious program files (executable files) to the Avira Malware
Research Center for advanced online scanning. After evaluation, these data are added to
the ProActiv behavioral analysis rule sets. In this way, you become part of the Avira
ProActiv community and contribute to the continuous improvement and refinement of
the ProActiv security technology. No data are sent if this option is disabled. This has no
effect on ProActiv functionality.

on the advanced online scan. All data transmitted during an advanced online scan is
included on the Internet page.
12.2.2.1. Application filter: Applications to be blocked
Under Application filter: Applications to be blocked you can enter applications which you
classify as harmful and which you want Avira AntiVir ProActiv to block by default. The
applications added cannot be executed on your computer system. You can also add
programs to the application filter for blocking via Guard notifications of suspicious
program behavior, by selecting theAlways block this program option.
Applications to be blocked
Applications
The list contains all applications which you have classified as harmful which you have
entered via the configuration or by notifying the ProActiv component. The applications
on the list are blocked by Avira AntiVir ProActiv and cannot be executed on your
computer system. An operating system message appears when a blocked program starts
up. The applications to be blocked are identified by Avira AntVir ProActiv on the basis of
the path specified and the file name, and are blocked irrespective of their content.
Input box
Enter the application you want to block in this box. To identify the application, the full
path, file name and file extension must be specified. The path must either show the drive
on which the application is located or start with an environment variable.
84
The button opens a window in which you can select the application to be blocked.
Add
With the "Add" button you can transfer the application specified in the input box to the
list of applications to be blocked.
Page 90
Reference: Configuration options
Note
Applications required for the proper operation of the operating system cannot be added.
Delete
The "Delete" button lets you remove a highlighted application from the list of
applications to be blocked.
12.2.2.2. Application filter: Permitted applications
The section Application filter: Permitted applicationslists the applications excluded from
monitoring by the ProActiv component: signed programs classified as trusted and
included in list by default, all applications classified as trusted and added to the
application filter: You can add permitted applications to the list in Configuration. You
also have the option of adding applications to suspicious program behavior via Guard
notifications by using the Trusted program option in the Guard notification.
Applications to be skipped
Applications
The list contains applications excluded from monitoring by the ProActiv component. In
the default installation settings, the list contains signed applications from trusted
producers. You have the option of adding applications that you consider to be
trustworthy via the configuration or via Guard notifications. The ProActiv component
identifies applications using the path, the file name and the content. We recommend
checking the content as malcode can be added to a program through changes such as
updates. You can determine whether a contents check should be performed from the
type specified: For the "Contents" type, the applications specified by path and file name
are checked for changes to the file content before they are excluded from monitoring by
the ProActiv component. If the file contents have been modified, the application is again
monitored by the ProActiv component. For the "Path" type, no contents check is
performed before the application is excluded from monitoring by the Guard. To change
the exclusion type, click on the type displayed.
Warning
Only use the Path type in exceptional cases. Malcode can be added to an application
through an update. The originally harmless application is now malware.
Note
Some trusted applications, including for example all application components of your
AntiVir program, are by default excluded from monitoring by the ProActiv component
even though they are not included in the list.
Input box
In this box you enter the application to be excluded from monitoring by the ProActiv
component. To identify the application, the full path, file name and file extension must
be specified. The path must either show the drive on which the application is located or
start with an environment variable.
The button opens a window in which you can select the application to be excluded.

Page 99
Avira AntiVir Professional
The FireWall section of Configuration is responsible for configuration of the Avira
FireWall.
12.4.1 Adapter rules
In the Avira FireWall, an adapter represents a software simulated hardware device (e.g.
miniport, bridge connection, etc.) or a real hardware device (e.g. network card).
The Avira FireWall displays the adapter rules of all existing adapters on your computer
for which a driver was installed.
A predefined adapter rule depends on the security level. You can change the security
level in the Online protection :: You can change the FireWall settings in the Control
Center or define your own adapter rules. If you have defined your own adapter rules, in
the FireWall section of the Control Center, the security level is set to custom.
Note
The default security level setting for all predefined rules of the Avira FireWall is
Medium.
ICMP protocol
The Internet Control Message Protocol (ICMP) is used to exchange error and
information messages on networks. The protocol is also used for status messages with
ping or tracer.
With this rule, you can define the incoming and outgoing blocked message types, the
behavior in case of flooding and the reaction to fragmented ICMP packets. This rule
serves for preventing so-called ICMP flood attacks, which results in an increase of the
CPU load of the attacked machine as it responds to every packet.
