– Program files (product update)
The Scheduler facility on the AntiVir server console allows you to create update jobs that
will be executed by AntiVir Updater at the specified intervals. Following the installation
of AntiVir server, an update job is created that will be executed by default at the
following interval: 60 minutes.
With every update order, the status of the virus definition files and the scanning engine
is checked and updated if necessary, product updates are carried out in accordance with
the configuration. You can initiate a manual product update from the context menu of a
server node on the AntiVir server console. A restart of the system after an update is
required only after a product update.
You can obtain updates via the following servers:
– directly from the Internet via a web server of Avira GmbH
– via a web server or file server on an intranet, which downloads the update
files from the Internet as the master server and supplies them to other servers.
This is useful if you want to update AntiVir Server on multiple computers on a
network. A download server on an intranet can be used to ensure AntiVir Server
is up-to-date on the protected servers using a minimum of resources. To set up a
functioning download server on an intranet, you need a server which is
compatible with the update structure of AntiVir Server.
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. The update is configured
on the AntiVir Server Console.
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 AntiVir products (including AntiVir Server) and can be obtained on
the Internet at http://www.avira.com.

8 Viruses and more
8.1 Viruses and other malware
Adware
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 circumventing 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.
The connection data allow many conclusions on the usage behavior and are problematic
in terms of data security.
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&ldots;
Bot-Net
A bot net is defined as a remote network of PCs (on the Internet), which 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., partly without the affected PC user's knowledge. The main
potential of Bot-Nets is that the networks can achieve dimensions on thousands of
computers and its bandwidth sum bursts 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. A form of an exploit for example are attacks from the Internet with the help of
manipulated data packages. Programs can be infiltrated in order to obtain higher access.
Hoaxes
19
Avira AntiVir Server
For
that are purportedly spread via email. These alerts are spread per 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. It has the function to
monitor a network and to protocol 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.
Macro viruses
Macro viruses 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 do consequently not attack executable files but they do attack the documents of
the corresponding host-application.
several years, Internet and other network users have received alerts about viruses
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.
20
Program viruses
Viruses and more
A computer virus is a program that is capable
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 his virulent code. The program execution of the host itself is not changed
as a rule.
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
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 can
consequently not 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.
to attach itself to other programs after
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. We are talking about 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 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.

Avira AntiVir Server
8.2 Extended threat categories
Dialers (DIALERS)
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 directly your telephone provider to block this number range
to be immediately protected against undesired dialers (0190/0900 dialers).
Avira AntiVir Server 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.
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.
22
Avira AntiVir Server detects computer games. If the Games option is enabled with a
check mark in the configuration under Extended threat categories, you receive a
corresponding alert if Avira AntiVir Server detects a game. The game is now over in the
truest sense of the word, because you can simply delete it.
Viruses and more
Jokes (JOKES)
Jok
es 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, Avira AntiVir Server
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 Extended
threat categories, a corresponding alert is issued if a joke program is detected.
Security Privacy Risk (SPR)
Software that maybe is able to compromise the security of your system, initiate
unwanted program activities, damage your privacy or spy out your user behavior and
might therefore be unwanted.
Avira AntiVir Server 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 Avira AntiVir Server 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.
Avira AntiVir Server detects "backdoor control software". If the option Backdoor
Clients is enabled with a check mark in the configuration under Extended threat
categories, you receive a corresponding alert if Avira AntiVir Server 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."
Avira AntiVir Server detects "Adware/Spyware". If the option Adware/Spyware is
enabled with a check mark in the configuration under Extended threat categories, you
receive a corresponding alert if Avira AntiVir Server detects such software.
Unusual Runtime Compression Tools (PCK)
Files that have been compressed with an unusual runtime compression tool and that can
therefore be classified as possibly suspicious.
23
Avira AntiVir Server
Avira AntiVir Server detects "Unusual runtime Compression Tools". If the option
Unusual runtime Compression Tools is enabled with a check mark in the
configuration under Extended threat categories, you receive a corresponding alert if
Avira AntiVir Server 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.
Avira AntiVir Server detects "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 Avira AntiVir Server 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.
Avira AntiVir Server detects "Phishing". If the option Phishing is enabled with a check
mark in the configuration under Extended threat categories, you receive a corresponding
alert if Avira AntiVir Server detects such behavior.
Application (APPL)
The term APPL refers to an application which may involve a risk when used or is of
dubious origin.
Avira AntiVir Server detects "Application (APPL)". If the option Application (APPL) is
enabled with a check mark in the configuration under Extended threat categories , you
receive a relevant alert if Avira AntiVir Server detects such behavior.

10 Reference: Configuration options
The configuration reference documents all configuration options available in Avira
AntiVir Server.
10.1 Scanner
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 Avira AntiVir Server. This means that Avira AntiVir
Server 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 setting is activated by default 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.
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
27
Avira AntiVir Server
With the
aid of this button, a dialog window 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 only 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.
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, but is always displayed in the
configuration and can be enabled: If the administered server does not have more than
one processor, the Scanner option is not used.
Follow symbolic links
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) which 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, Windows 2003 64 bit and
Windows Server 2003 64 bit!
28
Important
The rootkit scan is not carried out remotely.
Scan Registry
If this option is enabled, the Registry is scanned for references to malware.
Reference: Configuration options
Do not scan files and paths on network drives
Scan process
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 setting is activated by default 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.
10.1.1 Action for concerning files
Action for concerning files
You can define the actions to be carried out by Scanner when a virus or unwanted
program is detected.
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.
Primary action
Primary action is the action carried out when the Scanner finds a virus or an unwanted
program. If the option repair is selected but a repair of the file involved is not possible,
the action selected under Secondary action is carried out.
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.
29
Avira AntiVir Server
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.
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
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.
30
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 Deleteor 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.
10.1.2 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 carried out.
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
In this input box you can enter command line parameters for the program to be started
if necessary.
Reference: Configuration options
Event log
Use event log
If this option is enabled, an event report with the results of the scan is transferred to
Windows event logging 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.
10.1.3 Archives
10.1.4 Archives
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
31
Avira AntiVir Server
If this
(archive), even if the file extension differs from the usual extensions, and scans the
archive. However, for this every file must be opened - 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 are supported, which are marked in the archive list.
Limit 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.
option is enabled, the Scanner detects whether a file is a packed file format
Archives
In this display area you can set which archives the Scanner should scan. For this, you
must select the relevant entries.
10.1.5 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 on 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 entered 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.
32
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 which are
saved directly under the partition will be excluded from the scan, which does not apply
for 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.
10.1.6 Heuristic
This configuration section contains the settings for the heuristic of the Avira AntiVir
Server search engine.
Avira AntiVir Server contains 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
Avira AntiVir Server contains a highly powerful macro virus 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.

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, Avira AntiVir Server detects slightly less unknown malware, the
risk of false alerts is low in this case.
Medium detection level
This setting is activated by default if you have selected the use of this heuristic.
High detection level
If this option is enabled, Avira AntiVir Server detects much more unknown malware,
however false positives can also be expected.
10.1.7 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.
Note
To enable you to establish what actions the Scanner has carried out when viruses or
unwanted programs have been detected, a report file should always be created.
iVir Server contains a very powerful heuristic in the form of AntiVir AheAD
Reporting
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.
10.2 Guard
34
Reference: Configuration options
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
If this option is enabled, all files, irrespective of their content and their file extension,
are scanned for viruses or unwanted programs, i.e. 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 Avira AntiVir Server. This means that Avira AntiVir
Server 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 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. This setting is activated by default and is
recommended.
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 window 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.
35
Avira AntiVir Server
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.
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 unpacked and scanned.
Maximum number of files
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 1000KB is recommended.
Drives
Local Drives
When the option has been activated, files of local drives, such as HDUs, CD and diskette
drives, MO and ZIP drives, etc. only are monitored. This option is enabled as the default
setting and is recommended.
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!
36
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.
10.2.1 Action for concerning files
Action for concerning files
You can define the actions to be carried out by Guard when a virus or unwanted program
is detected.
Extended terminal server support
If this option is enabled, a dialog window appears during the on-access scan when a virus
or unwanted program is detected in which you can choose what is to be done with the
file concerned.
repair
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 the quarantine folder. 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 may be 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.
Deny access
Access is denied to the file. Guard logs the detection to the report file if the report
function is activated. In addition, the Guard writes an entry in the Event log, if this
option is enabled.
Default
Reference: Configuration options
37
Avira AntiVir Server
This button allows you t
o 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.
Automatic
If this option is enabled, then no dialog box for selecting an action appears following the
detection of a virus or unwanted program. Guard reacts according to the settings you
define in this section.
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, there are
more selection possibilities in the Quarantine manager.
Display detection alerts
If this option is enabled, then for each detection of a virus or unwanted program a
warning message appears.
Primary action
Primary action is the action carried out when the Guard finds a virus or an unwanted
program. If the option repair is selected but a repair of the file involved is not possible,
the action selected under Secondary action is carried out.
Note
The option Secondary action can only be selected if the option Repair was selected under
Primary action.
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.
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.
rename
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.
38
Warning
The affected file remains active on your workstation! It may cause serious damage on
your workstation!
Reference: Configuration options
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 the 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 option 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".

Event log
Use event log
When this option is enabled, an entry is added to the event log for every detection. The
administrator can identify detections and react accordingly. This option is enabled as the
default setting.
10.2.3 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 back-up solutions.
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.
Note
The entries on the list must not result in more than 6000 characters in total.
Warning:
The specified path and file name of the process should contain a maximum of 255
characters.
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.
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.
40
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.
Reference: Configuration options
Note
The entries in the list must have no more than 6000 characters in total.
Note
For each drive you can specify a maximum of 20 exceptions by entering the complete
path (starting with the drive letter).
E.g.: C:\Program Files\Application\Name.log
The maximum number of exceptions without a complete path is 64.
For example: *.log
\computer1\C\directory1
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 observe the following points:
– The file name can only contain the wildcards * (any number of characters) and
? (a single character).
– Directory names must end with a backslash \, otherwise a file name is assumed.
– The list is processed from top to bottom.
– Individual file extensions can also be excluded (inclusive wildcards).
– If a directory is excluded, all its sub-directories are automatically also excluded.
– 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.
– 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.
– In order to exclude files and folders on connected network drives from the Guard
scan, specify the UNC path you use to connect the network drive in the list of
exceptions.
\\<Computer name>\<Enable>\ - OR - \\<IP address>\<Enable>\
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!
41
Avira AntiVir Server
Note
With regard to exceptions on connected network drives, please note the following: 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.
Note
In case of dynamic drives which 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.
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 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.Local

Products to be skipped by Guard
In this display box, you can select products which are excluded by the Guard scan. All
applications, services or databases of the selected products are excluded from the
monitoring by Guard.
10.2.5 Heuristic
This configuration section contains the settings for the heuristic of the Avira AntiVir
Server search engine.
Avira AntiVir Server contains 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
Macrovirus heuristics
Avira AntiVir Server contains a highly powerful macro virus 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
Avira AntiVir Server contains a very powerful heuristic in the form of AntiVir AheAD
technology, which can also detect unknown (new) malware. If this option is activated,
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, Avira AntiVir Server detects slightly less unknown malware, the
risk of false alerts is low in this case.
Medium detection level
This setting is activated by default if you have selected the use of this heuristic.
High detection level
If this option is enabled, Avira AntiVir Server identifies far more unknown malware, but
you must also accept that there are likely to be false positives.

that uses script and programming languages to allow read and write access, both local
and remote, to settings on Windows systems. AntiVir Server supports WMI and provides
data (status information, statistical data, reports, planned requests, etc.) as well as
events and methods (stopping and starting processes) at an interface. WMI enables you
to download operating data from AntiVir Server and to control AntiVir Server . You can
request a complete reference guide to the WMI interface from the AntiVir Server
manufacturer. The reference file is available in PDF format when you sign a
confidentiality agreement.
