Welcome to avast! Antivirus 8.0

avast! Antivirus 7.0 introduced a number of new features and improvements which
made it even faster and even less resource-hungry than previous versions. New
hybrid cloud technologies such as streaming (real-time) virus database updates and
the new avast! FileRep gave you greater protection than ever. The Remote

Assistance feature enabled you to get help from anybody else with an internet

connection, enabling them to connect directly to your computer.

In avast 8.0, we’ve made improvements to the Behavior Shield and Remote
Assistance features, we’ve improved the hybrid cloud technologies and we’ve
redesigned and simplified the user interface. With the new AccessAnywhere feature,
you can access any other computer on which avast! Premier has been installed, and
control it remotely, provided it has been configured to allow you remote access.

We’ve also added the new Software Updater to help you keep all your software up
to date to prevent malware attacks which specifically target known vulnerabilities.
There’s also an optional Browser Cleanup tool for removing unwanted toolbars and
plug-ins.

Avast! Internet Security 8.0 additionally includes:

• Firewall - provides additional protection against hackers.

• Avast! SafeZone – a clean desktop where you can manage your sensitive

transactions in a safe, secure environment.

• Avast! AntiSpam Filter - gives you more control over your email.

• Command-line scanner - allows you to create and run scans without starting

avast and even before your operating system has started up.

Based on the award-winning avast! antivirus engine, avast! Internet Security
incorporates anti-spyware technology, certified by West Coast Lab’s Checkmark
process, as well as anti-rootkit and strong self-protection capabilities, but remains
one of the fastest and least resource-intensive antivirus solutions available with top­notch detection ability.

Like all avast! antivirus 8.0 products, avast! Internet Security 8.0 is based on several
real-time shields which continuously monitor your email and internet connections and
check the files on your computer whenever they are opened or closed. Once installed,
avast! runs silently in the background to protect your computer against all forms of
known malware. If everything is ok, you won’t even notice that avast! is running –
just install and forget!

How to install avast! Internet Security 8.0

The following pages describe how to download and install avast! Internet Security

Step 1. Download avast! Internet Security 8.0 from www.avast.com

It is strongly recommended that all other Windows programs are closed before
beginning the download.

If you are using Internet Explorer as your web browser, when the download starts
the box shown below will then be presented:

Clicking either “Run” or “Save” will start the download of the installation file to your
computer.

If you want avast! Internet Security 8.0 to be installed on your computer immediately
after the installation file has been downloaded, click “Run”.

In other web browsers, you may only have the option to “Save” the file. Clicking
“Save” will download the software to your computer but avast! will not be installed
at this time. To complete the installation process it will be necessary to run the
installation file so remember where it has been saved!

avast! Internet Security 8.0 – Quick Start Guide

6

Step 2. Install avast! Internet Security 8.0 on your computer

To install avast! Internet Security 8.0 on your computer, you need to run the
installation file. When you run the installation file (by clicking “Run” as described
above, or by double clicking the file saved on your computer) the following screen will
then be displayed:

Clicking “Run” again will take you to the avast! Installation screen.

By changing the language in the top-right corner, you can select your preferred
language for the installation.

You can then choose the type of installation. For most users, it is recommended to
select “Express Install”.

There is also a “Custom Install” option for more advanced users, which allows you to
tailor the installation according to your specific requirements, for example you can
select exactly which components to install and the language in which the program
will be installed.

avast! Internet Security 8.0 – Quick Start Guide

7

Also, if you have already purchased a license, you can insert it during the custom
install:

Here you have the option to use the program in trial mode, or to insert a valid
license:

• If you wish to use the program in trial mode, you will need to be connected to

the internet as the trial license will be automatically downloaded during the
installation. You will then be able to familiarize yourself with the program for a
trial period of 30 days, however you will need to insert a full valid license to
continue using the program after the 30 day trial period - see the next page.

• If you have already purchased a license and saved it on your computer, use

the “Browse” button to locate the license file on your computer. Click on it to
select it and then click “Open” and your license file will be automatically
inserted. You can now use the program for the duration of your license.

• If you purchased your avast antivirus with an activation code, you can enter it

here to activate your license.

Then click “Next” to continue.

avast! Internet Security 8.0 – Quick Start Guide

8

The final screen should confirm that your installation of avast! has been successfully
completed. Click “Finish”.

You will then need to restart your computer.

After restarting your computer, you will be asked to confirm what firewall mode
should be used for your network:

The three available settings determine what communication is allowed between your
network and other external networks.

The default mode is “Work/Medium Risk Zone” which means avast will decide which
external connections are allowed. The most secure setting is “Public” which will block
all incoming communication, or you can choose “Home” which will allow all
communication and is therefore recommended only if you are using your computer on
a local network with no external connections e.g. to the internet.

These three settings are all described later in this guide in the “Firewall” section.

On your desktop, you should now see the orange avast! icon and the
orange avast! ball in your system tray (close to the clock)

If you are using Windows Vista or later, with the sidebar option, you
will also see the avast sidebar icon. This tells you the current status of
your avast program and you can drag & drop files onto the avast icon
if you want them to be scanned.

avast! Internet Security 8.0 – Quick Start Guide

Inserting a License

If you did not insert a license during the installation, the program can still be used
free of charge for a 30-day trial period, however, if you wish to continue to use the
program after the trial period, it will be necessary to purchase a license which must
then be inserted into the program.

Licenses can be purchased for 1, 2, or 3 years and for up to 3, 5, or 10 computers in
your home or on your small home/office network.

For larger networks and corporate users, we recommend our centrally managed
products which provide central administration of all the computers on the network.
More information about our centrally managed products can be found on our website,

www.avast.com

To purchase a license, open the “Maintenance” tab, then choose “Subscription” and
click on “Purchase now”. Then just follow the on-screen instructions to select and
purchase your license.

After receiving your license file, you just need to double-click to open it and your
license will be inserted into your program automatically. Alternatively, save the file on
your computer, open the avast! interface and click on the Maintenance tab. Next click
on ”Subscription” and then on “Insert license file”.

avast! Internet Security 8.0 – Quick Start Guide

10

A new window will open in which you can browse your computer to locate your
license file.

Once you have located it, double click on it and it will be automatically inserted into
the program.

If you have purchased a multi-license to protect several computers, you will need to
carry out the same process on each computer where avast! is installed e.g. by
forwarding the email with the license file attachment to each user, or by saving the
license file on a shared drive, USB stick etc.

Once the license is inserted, you can continue to receive automatic updates so that
you remain protected against the very latest threats.

avast! Internet Security 8.0 – Quick Start Guide

11

Protection Status

When you open the program’s main window, it will tell you the current security status
of your computer. Normally, the window should appear as shown below.

If the main window appears as shown below, it means that your virus definitions may
not be up to date or one or more of your real-time shields may be turned off. You can
solve this by clicking on “Resolve”.

avast! Internet Security 8.0 – Quick Start Guide

12

“Unsecured” means all of your real-time shields are turned off. Use the “Resolve”
button to turn them all on so that your computer is fully protected.

More about the real-time shields

The real-time shields are the most important part of the program, as they are working
continuously to prevent your computer from becoming infected. They monitor all of your
computer's activity, checking all programs and files in real-time - i.e. at the moment a
program is started or whenever a file is opened or closed. Click on the “Security” tab to see
the current status of all the Shields.

Normally, the real-time shields start working automatically whenever your computer is
started. The presence of the orange avast! icon in the bottom-right corner of your computer
screen tells you that the real-time shields are working. Any of the shields can be turned off
at any time, but this is not normally recommended as it may reduce the level of your
protection.

Click on any shield icon to access the shield controls and to see information about what has
been scanned and any threats that have been stopped.

avast! antivirus 8.0 contains the following real-time shields:

avast! Internet Security 8.0 – Quick Start Guide

13

File system shield - checks any programs at the moment they are started and other files at

the moment they are opened or closed. If anything suspicious is detected, the file system
shield will prevent the program from being started or the file from being opened to prevent
any damage being caused to your computer and data.

Web shield - protects your computer from viruses while using the internet (browsing,

downloading files etc) and can also block access to infected web pages. If a virus is detected
while downloading a file from the internet, the download will be stopped to prevent the
infection from reaching your computer.

Mail shield - checks incoming and outgoing email messages and will stop any messages

containing a possible virus infection from being accepted or sent.

Network shield - monitors all network activity and blocks any threats that are detected on

the network. It also blocks access to known malicious websites.

P2P shield - checks files downloaded using common peer-to-peer (file sharing) programs.

IM shield - checks files downloaded by instant messaging or "chat" programs.

Behavior shield - monitors all activity on your computer and detects and blocks any

unusual activity that might indicate the presence of malware. It does this by continuously
monitoring your computer's entry points using special sensors to identify anything
suspicious.

Script shield - monitors all scripts that try to run on your computer, whether the

script is executed remotely e.g. while browsing the internet, or locally by opening a
file on your computer.

avast! Internet Security 8.0 – Quick Start Guide

14

Cloud Intelligence

With avast! Cloud Intelligence, you can benefit from the global avast! CommunityIQ
network, which provides information about possible suspicious files and also allows
new threats to be detected and neutralized almost as soon as they appear.

Reputation Services

If this option is enabled, avast will check if a file is safe even before it is opened, by
checking its database of known files. Whether the file is considered safe or not will
be determined by how many other users have the file, and for how long it has
existed.

Streaming (real-time) Updates

Any antivirus program is only as good as its database of known virus
definitions. This is what the program uses to identify threats to your
computer, which is why it is important to ensure the virus definitions are
regularly updated.

By enabling Streaming Updates, you can make sure that new virus definitions
are sent to you in real-time, rather than waiting for the next regular update.
As your virus database will be continuously updated, this will give you even
more protection against the very latest threats.

By default, avast! is set to update both the engine and virus definitions
automatically whenever a new version is available. To disable Streaming
Updates, click on “Maintenance” then “Updates”.

avast! Internet Security 8.0 – Quick Start Guide

15

Here, you can also check the current version of the program and when the virus
definitions were last updated.

The “engine” is the part of the program that scans your computer for potential
threats based on the virus definitions. The “program” means what you can see – the
user interface which is used to control what the program does.

You can manually update either by clicking on the green arrow. Note that clicking on
“Update Program” automatically updates both the program and the program engine
and virus definitions.

Reputation Services and Streaming Updates can be enabled or disabled by opening the
Settings in the top-right corner and selecting “Cloud Services”.

Remote Assistance

The remote assistance tool enables you to give another person remote access to
your computer. This can be useful if you are having any difficulties and you want
another person to take control of your computer to help resolve the problem.

If you need to request assistance from another person, click “Allow Remote Control”.

Avast! will generate a code that you then need to provide to the assisting person. To
transfer the code to the other party please use e.g. telephone, e-mail or chat. By
sending the code you are granting remote access to your computer to another
person. After the person takes control, this dialog disappears automatically.

If you will be providing the remote assistance, click on "Control Remote Computer".
Enter the code which you receive from the person needing assistance, then click the
"Connect" button. When the connection is established, this dialog disappears and the
remote desktop window appears.

To close the connection, click the following link or press the Alt+Shift+End shortcut.

avast! Internet Security 8.0 – Quick Start Guide

17

AccessAnywhere

Very similar to the Remote Connect feature, this allows you to access and control a
computer
remotely from another location. If you are a frequent traveler and need to access
your computer back at home while you are away, you can do so via any other
computer on which avast 8.0 is installed.

Unlike Remote Connect, the connection is established by the remote user, not from
the computer which is being accessed. However, the computer which is to be
accessed, must be running avast! Premier and must have first been configured to be
remotely accessible. This can only be done in avast! Premier.

To remotely connect to another computer which has been correctly configured, just
click on the button to remotely control a computer and then enter the email and
password for the avast! Account to which it is connected.

Another use of AccessAnywhere is where a friend or family member regularly needs
your help but does not want to use the Remote Connect feature. In such a case,
provided they have installed avast! Premier, you can configure their computer in
advance to allow you remote access.

In order to connect to their computer remotely, you would only need to know the
logon credentials for the avast! Account with which the computer is connected. By
first connecting the other person’s computer to your own avast! Account, you would
be able to control it remotely by entering your own avast! Account credentials.

avast! Internet Security 8.0 – Quick Start Guide

18

Manually scanning your computer

To carry out a manual scan of your computer, select the “Scan computer” tab. This
will open the “Scan Now” screen as shown below.

avast! Internet Security 8.0 comes with a number of pre-defined scans installed by default.

Quick scan - this will perform a scan of just your system partition (normally the C:\ drive on

your computer) and will normally be sufficient to detect the majority of malware. By default,
only files with "dangerous" extensions are scanned, e.g. files with extensions such as "exe",
"com", "bat" etc. Only those areas at the beginning and at the end of a file, where infections
are normally found, are tested.

Full System Scan - This performs a more detailed scan of all your computer's hard disks.

By default, all files are scanned according to their content, in other words, avast! looks
inside every file to determine what type of file it is and whether it should be scanned. The
whole file is tested, not just those parts of the file at the beginning or at the end where
infections are normally found. This is useful if you suspect you have an infection which was
not detected by the quick scan.

Removable Media Scan - this will scan any removable media that is connected to your

computer, such as USB flash drives, external hard drives etc. It will scan the media to detect
potential "auto-run" programs that may try to launch when the device is connected.

Select folder to scan - this option enables you to scan just a specific folder or multiple

folders.

To run one of the pre-defined scans now, just click "Start". Alternatively, by clicking on
“Settings”, you can schedule the scan to be run on a regular basis, or just once at a later
date and time. The other settings screens can be used to further customize the scan, or by
clicking on “Create custom scan” you can create a new scan with all the required settings.

Creating a custom scan

By clicking on the "Create Custom Scan" button, you can define a completely new
scan with its own scan parameters. A new window will open, where you can create a

avast! Internet Security 8.0 – Quick Start Guide

19

name for the new scan, specify which parts of your computer and which types of file
should be scanned.

By default, the area to be scanned is set as "All hard disks". To select a new area to
be scanned, just open the drop-down menu and select the additional area to be
scanned. To remove an area, click on it once and then click "delete". You can also
specify how avast! should recognize potentially suspicious files that should be
scanned, either by checking the file extension or by checking the actual content:

Content – if this is checked, avast! will look inside every file to determine what type of file it

is and whether it should be scanned.

Name extension – if this is checked, only files with extensions such as "exe", "com", "bat"

etc. will be scanned.

On this page, you can also access the other scan settings, for example, if you want
to schedule a regular scan or a scan to run just once at a specific time. You can also
exclude specific folders or files from being scanned, and define what action should be
taken in the event that a virus is detected e.g. delete the file, or move it
automatically to the virus chest.

You can also create reports of the files that were scanned and any errors that
occurred during the scan. The other settings can be used to adjust the speed and
depth of the scan.

New in avast! 8.0, you can now also specify that a scan should not start if your
computer is running on batteries.

avast! Internet Security 8.0 – Quick Start Guide

20

What to do if a virus is found

At the end of the scan, if the program has detected a suspicious file, the message
“Threat detected” will be displayed – see below.

To see more information about the suspicious file and the available options, click on
“Show Results”.

You will then see a list of the files which avast! considers suspicious and you will be
able to specify what action to take in respect of each one, e.g. Delete, Move to virus
chest etc. Once you have specified the action to be taken, click “Apply”.

The RECOMMENDED OPTION is to move the file to the Virus Chest. This is a special
quarantine area which can be used to safely store infected or suspicious files until
you decide it is safe to delete it. Files stored here cannot cause damage to your
other files or your computer. Here it can possibly be repaired before moving it back to
its original location.

By default, suspicious files which are detected by the real-time shields are moved to
the virus chest automatically.

You can view the scan results again at any time by going to the “Scan Logs” section
then selecting the scan that you wish to review.

and you will no longer be at risk of malware that targets out-dated software.

avast! Internet Security 8.0 – Quick Start Guide

22

Process virtualization (Sandbox)

The avast! Sandbox allows you to browse the web or run another application in a
completely safe environment. This is especially useful when visiting high-risk web
sites, whether accidentally or deliberately, as the browser will be completely
contained within the sandbox, preventing any damage to your computer.

The sandbox can also be used to run any other applications which you think may be
suspect – you can run the program inside the sandbox to determine whether or not it
is safe while remaining completely protected against any malicious actions that it
may try to carry out.

To run an application or to browse the web using the sandbox, just click on “Run a
virtualized process” then browse the files on your computer to find the required
application e.g. Internet Explorer. The browser or other application will then open in a
special window with a red border, indicating that it is being run inside the sandbox.

In the Sandbox Settings, you can further define applications that should always be
run in virtualized mode, and trusted applications that should never be virtualized.

In the main Program settings, in the “Browser Integration” tab, you can further
specify that your browsers should always be run in the Sandbox to ensure you are
always protected while surfing the web.

avast! Internet Security 8.0 – Quick Start Guide

23

Avast! will launch an application automatically in the Sandbox if it detects anything
suspicious. In the AutoSandbox settings, you can change this so that avast! will ask
you first:

In the settings, the AutoSandbox can also be disabled completely, or you can specify
any files or applications that should be excluded and never run automatically in the
Sandbox.

You can also run an application in the sandbox without opening the avast! user
interface. Just right click on the application which will open the context menu bottom
left.

To run the application inside the sandbox, select “Run virtualized” and the application
will start inside a window with a red border. To ensure the application runs inside the
sandbox every time it is started, select “Always run in sandbox”.

Right-clicking on an application that is already inside the sandbox will open the
context menu above right. The application can then be run one time outside the
sandbox, or it can be moved out of the sandbox completely so that it will be run in
the normal environment every time it is started.

avast! Internet Security 8.0 – Quick Start Guide

24

Process Virtualization (SafeZone)

The avast! safeZone is an additional security feature that allows you to browse the
web in a private, secure environment, invisible to the rest of your system. For
example, if you do your banking or shopping online, or other security-sensitive
transactions, you can be sure that your personal data cannot be monitored by
spyware or key-logging software.

Unlike the Sandbox, which is intended to keep everything contained inside so that it
cannot harm the rest of your system, the avast! SafeZone is designed to keep
everything else out.

To open the secure SafeZone desktop, just go to the "Tools" tab and click "Switch to
SafeZone".

When you switch to SafeZone, the SafeZone web browser will start automatically. The
SafeZone browser is a special browser without any additional components such as "plug-ins"
which are often used to distribute spyware.

When you are done, click on the orange avast! icon in the bottom left corner and select “Turn
off SafeZone” to close the browser and return to your normal desktop. Your browser
settings and any files that you have downloaded will be saved automatically and will be
there the next time you open it. If you don't want anything to be saved, click the "Reset
SafeZone" button and everything will be deleted. The contents of the SafeZone, including all
browser settings, will be reset to their original state.

Alternatively, you can just click the “Switch back” button on the taskbar (the white
arrow next to the clock) which will return you to your normal desktop without
terminating your web browser, so you can return to it later.

avast! Internet Security 8.0 – Quick Start Guide

25

Browser Protection

If you have installed Google Chrome, the avast! Web Rep and phishing filter are
automatically installed during the installation of avast! antivirus. Either of these can
be uninstalled or installed for any supported browser by opening "Settings", selecting
“Browser integration” and then just clicking "Uninstall" or “Install”. Here you can also
see whether your Internet browser is supported, before you try to install it.

Alternatively, you can enable or disable just the avast! WebRep, or just the phishing
filter in the program settings:

The WebRep is based on information received from the global avast! user community
related to the content and security of visited websites, to help improve the browsing
experience of all users. You can contribute your own feedback by “voting” on the
content and security of websites that you visit.

avast! Internet Security 8.0 – Quick Start Guide

26

When you visit a website, you will see a sequence of three bars (red, yellow, or green)
which tell you how the website has been rated, or when you do a search using one of
the popular search engines, you will see the same color-coded indicator next to each
of the listed results.

The color of the indicator tells you whether the site is rated as "good" (green),
"average" (yellow), or "bad" (red). The number of bars that are highlighted indicate the
strength of the rating. One, two, or three highlighted bars represent a small, limited,
or large number of votes.

Clicking on the colored indicator will open a box where you can see more information
about how the site has been rated and where you can also submit your own vote.

On the left side, you can see the overall rating. Below the rating, you can see smaller
icons which represent the categories that the site belongs to.

On the right side, you can submit your own vote. Here you can see a single bar
divided into five colored segments which you can use to assign a more detailed rating
to the domain. Below this bar you can again find the category icons. Click on one or
more icons to assign the domain to the relevant categories, then finally click on
"vote" to submit your rating.

avast! Internet Security 8.0 – Quick Start Guide

27

Browser Cleanup

Often, when you install free software it comes with other, possibly unwanted add­ons. In most cases, a new Browser Toolbar is installed. Some of these may be useful,
however, in general they are used to analyze your browsing behavior and present you
with specific ads.

avast! Browser Cleanup will show you a list of your browser toolbars, together with
their user rating, and will give you the option to disable them, or to fully remove
them. It will also give you the option to restore your browsers settings, such as your
homepage and default search provider. So avast! Browser Cleanup is a very useful
tool which will help to keep your Internet browsing experience fast and reliable.

Just click the button to start the avast! Browser Cleanup and it will check all your
installed browsers for added toolbars.

If no additional toolbars or other add-ons are detected, your browser status will be
reported as “Clean”.

Alternatively, if any add-ons are detected which have a low user rating, your browser
status will be either yellow or red with the word “Attention”.

• Yellow means that add-ons may have been manually removed, but there may

still be some relics left behind which have not been fully removed.

• Red means that one or more Internet browsers appear to contain add-ons and

products that have a poor user rating and which are removable.

You can remove the add-ons individually and they will be removed from all browsers,
or you can click one button to remove all of them and reset all your browser settings
to their default values.

avast! Internet Security 8.0 – Quick Start Guide

28

If you choose to Remove an add-on, this permanently deletes the add on, which
cannot be reversed. However, only add-ons with a bad, or very bad rating can be
removed.

Alternatively, you can use the tabs on the left to disable any unwanted add-ons for
each specific browser. Disabling an add-on only has the effect of turning it off and
can be reversed later by enabling the add-on again.

After selecting a specific browser, you will then see a list of all the installed add-ons
for that particular browser, together with their user rating. You can disable any which
are not wanted, or you can completely reset the browser settings to their default
settings.

By checking the box at the top of the page, you can choose to exclude any add-ons
that have a good user rating, so you will see only those whose rating is not good.
You can then decide what action to take for the others individually.

Firewall

avast! Internet Security includes a fully integrated firewall which can be controlled
directly from the avast! user interface.

The firewall monitors all communication between your computer and the outside
world and blocks unauthorized communication based on a number of "allow" and
"deny" rules. In this way, the firewall can prevent sensitive data from leaving your
computer and can also block attempted intrusions by external hackers.

On this page, you can adjust the firewall security settings to limit external
connections according to the environment in which the computer is being used.

Three security levels are defined:

• Home/Low Risk Zone - suitable when using your computer as part of a

home/private network. If this setting is selected, the firewall will allow all
communication with the network.

• Work/Medium Risk Zone - suitable for when your computer is connected to a

wider public network, including direct connections to the internet. This is the
default setting, and if selected, the firewall will allow communication in and
out only if allowed by the “Application Rules”. If no rule has been created, you
will be asked to confirm whether or not communication with a particular
application should be allowed.

• Public/High Risk Zone - suitable when using your computer to connect to a

public network and where you want to ensure the maximum level of security.
This is the most secure setting, and if selected, no incoming communication
will be allowed. This setting makes your computer effectively invisible to
others.

You can adjust the level of security by either clicking on the relevant icon, or by
clicking on the orange slider and moving it to the left or right while holding the mouse
button down.

On this page, you can also turn off the firewall completely, either permanently or for
a specified period of time by clicking the Stop button and selecting the required
option. Click Start to turn it on again.

A screen similar to this one will also appear whenever a new network connection is
detected. You will then be able to set the level of security for the new network and
you can specify that this should be remembered so that you will not be asked again
the next time the same network is detected.

Firewall Statistics

In the graph at the bottom of the page, you can see a real- time representation of
the amount of incoming and outgoing data.

To see a more detailed view, click on “Show Statistics History”. On the Statistics
screen, you can view the data for the firewall, antispam filter or any of the real-time
shields over the period selected. To change the scale of any part of the graph, click
on the vertical line and drag it to the right. To return to the previous view, just click
on “Show all” and the previous view will be restored.

On the left side of the screen, you can see the other firewall options which are
described in the program help.

AntiSpam Filter

The avast! AntiSpam filter analyzes all incoming emails to determine whether they
are legitimate or unsolicited spam messages. Messages identified as spam will be
marked as such before being delivered to your inbox. If you are a user of Microsoft
Outlook, you can specify an alternative folder to which junk email should be moved if
it is confirmed as spam– see the next section.

By default, avast! will check all incoming emails against an online database of global
spam messages before carrying out additional heuristic and other checks to identify
other potential spam. A message will be inserted into the heading of any messages
identified as spam before they are delivered to your inbox.

You can adjust the sensitivity of the heuristic checks level by clicking on the sequence
of orange bars.

Increasing the sensitivity will increase the probability of detection, but will also
increase the probability of the occasional false positive – if you find that some
legitimate emails are being marked as spam, reducing the sensitivity should help.

Trusted email contacts can be added to the whitelist. Messages from contacts on the
whitelist will never be marked as spam and will be delivered normally to your inbox.
Alternatively, adding an email address to the blacklist will ensure that emails from
that particular sender will always be marked as spam. Click on “Expert Settings” then
“Whitelist” or “Blacklist” and enter the relevant address.

Finally, on the Main Settings page you can specify exactly how suspected spam
emails should be marked, e.g. ***SPAM***. This can be used to create a rule in your
email client, for example to automatically move marked emails to another folder.

Microsoft Outlook

The avast! AntiSpam filter works as a plug-in to Microsoft Outlook, which means you
can control some of the features directly through Outlook.

When you open Outlook after installing avast! Internet security, you will notice some
additional options on the Outlook toolbar:

settings. By default this folder is called “avast! Junk”.

To move a message to the Junk folder, it is necessary to first highlight the message,
then clicking on “Spam” will result in the message being moved. The “avast! Junk”
folder will be created automatically when needed and added to the Outlook folders
structure.

Avast “System Tray” Icon

The orange avast! icon located in your computer’s system tray can be used to access
various features without opening the main user interface. If you right-click on the
avast! icon, a short menu will appear, as shown below.

You can choose to open the main interface and use the program as normal, or select
any of the other options directly from the menu.

• By selecting “avast! shields control”, you can turn off all of the shields

permanently, or for just the selected period of time.

• If “Silent/gaming mode” is activated, avast! will run automatically in silent mode if

a full-screen application is running. This means your games or other full-screen
applications will not be interrupted with annoying popups or other messages.

• If you select “Update”, you can choose to update your program, or you can update

just the scanning engine and virus definitions.

• You can also choose to see the last popup message that was displayed or by

clicking on “Subscription Information”, you can see the status of your current
subscription, insert your license, or purchase a new license.

• Finally, by clicking on “About avast”, you can see general information about your

avast security application.

The command-line scanner

The command-line scanner enables you to manually run a scan of your computer
without starting the avast! interface and even before your operating system has
started. The command-line scanner uses the same avast! scanning engine to detect
potential malware infections so the results are exactly the same as running a scan via
the normal program interface. The avast! command-line scanner, ashCmd.exe, is
normally installed in the directory C:\program files\AVAST Software\Avast.

34

A scan is run from the command prompt using various switches and parameters. To
see a description of the parameters, locate the ashCmd file and double click on it.
This will open a new window in which the various parameters are displayed. A list of
all the parameters can also be found in the avast! program Help.

• Here you can also request Remote Assistance from another avast user, which is

described in detail in the previous section.

• Finally, from here you can also open the Program Help in full.

There is an additional feature in avast which allows you to generate a support
package to help our support engineers to troubleshoot the problem.

You can select what information to include in the package, but as a minimum, it is
recommended to include the basic information and log files, then click on “Generate
Now!”. The data package generated will be saved to a special folder on your
computer and can then be sent by email to the avast support team.

You can also generate “Minidumps” of “Full dumps” which will include much more
comprehensive information about your system and will therefore be much larger.
These files are too large to be sent by email and would need to be provided using
other File Transfer tools. Minidumps or Full dumps should therefore be generated
only if specifically requested by the avast! support team or other person providing
technical assistance.
