2 Product Information
You are responsible for numerous workstations and servers in your network but you are
only human. The servers are the heart of the network. So if viruses can freely penetrate
and spread on your servers, your network is only a step away from breakdown. This is
where AntiVir products for servers come in.
UNIX computers are more often used as file servers or email gateway servers. Thus they
transfer and store files that have no connection to UNIX, e.g. Office documents and email
attachments. So, viruses can access a server through a Windows Client and freely cause
damage.
Avira AntiVir Server/ Professional is a comprehensive and flexible tool for confronting
viruses and unwanted programs and for reliable protection of your systems.
Right from the beginning, two really important hints:
Losing valuable files usually has dramatic consequences. Not even the
best antivirus software can fully protect you against data loss.
Ensure that you make regular backups of your files.
An antivirus program can be reliable and effective only if kept up to
date.
Ensure that you keep your AntiVir programs up to date using
automatic updates as described in this user guide.

Avira GmbH Avira AntiVir Server/ Professional (UNIX) 6

AntiVir Engine
AntiVir Engine essentially represents the scanning and repairing modules of Avira
software. These are also used by the other AntiVir products.
AntiVir Guard
AntiVir Guard runs as a daemon process. It permanently monitors all user access in the
network (on access) and it protects the files against viruses and unwanted programs. It
immediately blocks access to infected files which can be automatically renamed, repaired
or moved.
AntiVir Command Line Scanner
AntiVir CLS can always be launched from the command prompt (on-demand). Infected
files and suspicious macros can be isolated, cleaned or deleted using a number of options.
It can be integrated and used within scripts.
Avira Updater
Avira Updater downloads current updates from the AntiVir web servers and installs them
at regular intervals, manually or automatically. It can also send update notifications by
email. You can update Avira AntiVir Server entirely or only certain components:
signatures, engine, scanner.

Copy the license file hbedv.key to the installation directory on your system
./tmp/antivir-server-prof-<version>
or in ./tmp/antivir-workstation-prof-<version>
3.3 Installing AntiVir
AntiVir is automatically installed using a script. This script performs the following tasks:
• Checks integrity of the installation files.
• Checks for the required permissions for the installation.
• Checks for an existing version of AntiVir on the computer.
• Copies the program files. Overwrites existing obsolete files.
• Copies AntiVir configuration files. Existing AntiVir configuration files are inherited.
• Optional: it creates a link in /usr/bin, so that AntiVir can be called from any folder
without needing a given path.
• Optional: it installs the resident scanner AntiVir Guard and the dazuko module.
• Optional: it installs a Gnome plug-in.
• Optional: it installs Avira Updater.
• Optional: it configures an automatic start for Avira Updater and AntiVir Guard on
system start-up.
• Optional: it installs the plug-in for Avira Security Management Center.
Preparing Installation
Login as root. Otherwise you do not have the required authorization for installation
and the script returns an error message.
Go to the directory in which you unpacked AntiVir:
cd /tmp/antivir-server-prof-<version>
or
cd /tmp/antivir-workstation-prof-<version>
Installing AntiVir (example for AntiVir Server)
Type the command:
./install
You can also perform the installation without having a license key from the
beginning. You can copy the license file at any time to the AntiVir program
directory /usr/lib/AntiVir.
For using Avira AntiVir Server/ Professional v.3 with AntiVir Guard, we
recommend and support dazuko3/dazukofs.
The installation script will also install dazuko3, if it detects the
needed build components on your system. If the installation script
cannot detect a supported linux kernel version, you can only install Avira
AntiVir Server/ Professional without AntiVir Guard. AntiVir Guard can be
easily installed later. For more details, see The Dazuko Kernel Module –
Page 38.

Avira GmbH Avira AntiVir Server/ Professional (UNIX) 11

3.4 Reinstalling and Uninstalling AntiVir
You can launch the installation script at any time. There are several possible situations,
such as:
• Later installation of some components, e.g. AntiVir Guard or Avira Updater.
• Activating or deactivating the automatic start of Avira Updater or AntiVir Guard.
Reinstalling AntiVir
The procedure applies to all above mentioned cases:
3First of all, you have to make sure that AntiVir Guard is stopped:
/usr/lib/AntiVir/avguard stop
Open the temporary directory where you unpacked AntiVir Server:
cd /tmp/antivir-server-prof-<version>
or, for AntiVir Professional:
cd /tmp/antivir-workstation-prof-<version>
Type:
./install
 The installation script performs as described in Installing AntiVir – Page 10).
Make the changes you need during installation procedure.
 AntiVir is installed with the required features.
Uninstalling AntiVir
You can use the uninstall script, located in the temporary AntiVir directory, to remove
Avira AntiVir Server/ Professional. The syntax is:
uninstall [--product=productname] [--inf=inf-file] [--force]
[--version] [--help]
where productname is Guard.
Open the AntiVir directory:
cd /usr/lib/AntiVir
Type:
./uninstall --product=Guard
 The script starts uninstalling the product, asking you step by step, if you want to
keep backups for the license file, for the configuration files and logfiles; it can also
remove the cronjobs you made for Guard and Scanner.
Answer the questions with yor nand press Enter.
 Avira AntiVir Server/ Professional is removed from your system.

Avira GmbH Avira AntiVir Server/ Professional (UNIX) 15
3.5 Integration in AMaViS
"A Mail Virus Scanner (AMaViS)" project (http://www.amavis.org/) is already prepared
for integration with the AntiVir Scanner. You can either install AMaViS after installing
AntiVir, for automatic detection, or explicitly activate AntiVir support during AMaViS
installation using the option --enable-all or --enable-hbedv for the command
./configure.
Please note that AMaViS uses the Command Line Scanner and runs it as a
separate process for every message. Unfortunately, this method is not as
efficient as a dedicated email scanner. For an environment with higher
throughput requirements, you should consider integrating Avira AntiVir
MailGate or SAVAPI-based products.
You need a license to integrate the Command Line Scanner with AMaViS.
This allows you to generate antivirus scan services for other computers.

Avira GmbH Avira AntiVir Server/ Professional (UNIX) 16
4 Configuration
You can adjust AntiVir Server/ Professional for optimum performance. You can make the
main adjustments immediately after installation. The most common settings are
suggested. You can modify these settings anytime, to adjust the product to your
requirements.
After a short overview, you will be guided step by step through the configuration process:
• Description of the configuration files:
- Configuration of AntiVir Guard in avguard.conf – Page 16
-Configuration of the Command Line Scanner in avscan.conf – Page 22
- Scanner specific configuration in avguard-scanner.conf – Page 26
- Configuration of Avira Updater in avupdate.conf – Page 27
• Testing AntiVir Server/ Professional – Page 28, after completing the configuration.
4.1 Configuration Files
The configuration is defined in four files:
•/etc/avira/avguard.conf configures the on-access scanner.
•/etc/avira/avscan.conf configures the on-demand scanner.
•/etc/avira/avguard-scanner.conf configures Savapi3.
•/etc/avira/avupdate.conf defines the automatic updates.
This part describes the structure of AntiVir Server/ Professional configuration files.
AntiVir Server/ Professional reads these files on program start-up. It ignores empty lines
and commented lines beginning with #.
The program is provided with default values, which are important for many procedures.
Some options can be deactivated with a # at the beginning of the line (commented) or can
be set with default values. These can be activated by removing the # character or by
changing the values.
4.1.1 Configuration of AntiVir Guard in avguard.conf
This section provides a short description of the entries in avguard.conf . The settings
affect only the behavior of AntiVir Server/ Professional and no other AntiVir programs.
The settings can be made directly in the configuration files or as
parameters when using the Command Line Scanner.
The parameters given in command lines take precedence of those
saved in configuration files.
You must restart the AntiVir Guard if you modify any values
manually in the configuration files. The changes only take effect after
a restart.
Type:
/usr/lib/AntiVir/avguard restart

Avira GmbH Avira AntiVir Server/ Professional (UNIX) 17
Ondemand
Mgmt
Act as daemon for on-demand scans:
If OndemandMgmt is active, the Guard acts as daemon for on-demand scans. On-access
scanning becomes inactive. This option is not active by default.
OndemandMgmt yes
Num
Daemons
Number of daemons:
The number of simultaneous AntiVir Guard daemons can be set between 3 and 20. The
default is 3 and it is appropriate for smaller standard computers. For servers with high
traffic, a larger number would be necessary:
NumDaemons 3
If the value is 0, AntiVir Guard is deactivated.
Repair
Concerning
Files
Repairing files:
AntiVir Guard is trying to repair infected files immediately after access. If this fails, access
is blocked. The following option must be active:
RepairConcerningFiles yes
It is not activated by default.
AlertAction Action when detecting viruses or unwanted programs:
If RepairConcerningFiles is not set or repair is not possible, access to the file is
blocked and the action is logged. The following options define the actions of AntiVir
Guard:
•none or ignore: no further action
•rename or ren: renaming the file by adding the .XXX extension.
•delete or del: delete the concerning file.
•quarantine: move the concerning file into quarantine, if you defined one (see
below).
You can select only one of these options. If more than one is activated, AntiVir applies the
last one selected in the configuration file. Default:
AlertAction none
Quarantine
Directory
You have to define the quarantine directory, if you want to use the quarantine option
for AlertAction (see above). Default is:
QuarantineDirectory /home/quarantine
AccessMask Access mask (only for dazuko2):
This option sets the access type of AntiVir Guard, when scanning files for viruses or
unwanted programs:
• 1: Scanning a file when opened
• 2: Scanning a file when closed
• 4: Scanning a file when executed
For setting more access types at the same time, you have to add the above values. For
example, to scan files when opened and when closed, the value has to be 3 (default).

IncludePath Scanned directories (only for dazuko2):
AntiVir Guard scans the files in the specified directories, including their subdirectories.
Usually, the data for the different users is in /home:
IncludePath /home
You can specify only one folder in a command line. You can enter more folders by typing
the command for each one. Example:
IncludePath /var/tmp
IncludePath /tmp
ExcludePath Excluded directories:
AntiVir Guard can exclude certain folders when scanning. For example, a folder
containing temporary files of AntiVir components. There is no default setting.
You can specify only one path in a command line (trailing slash necessary). You can enter
more, by typing the command for each one. Example:
ExcludePath /home/log/
ExcludePath /pub/log/
Temporary
Directory
Temporary location of Guard files:
Temporary files of the Guard are written in this directory. Example:
TemporaryDirectory /tmp
ScanMode Configuring files to be scanned:
This entry sets the procedure to determine whether a file is to be scanned or not. The
available methods are:
•extlist: scan only files with certain extensions;
•smart: scan files based on both their name and file type;
•all: always scan files, of all types and names.
The default is:
ScanMode all
ArchiveScan Scanning archives on-access:
AntiVir Guard scans archives when opened, depending on the setting for
Please note that AntiVir Guard is able to react to these situations and
to scan files, only if the kernel module supports these events. Not
every operating system supports all events in every kernel version.
Moreover, some kernel modules offer the possibility to activate or
deactivate certain events. Independent from the use of the other
events, we recommend that you always keep the option Scanning
files when opened activated.
If no folder is specified, AntiVir Guard will not start!
Dazuko3 ignores this option. For dazuko3 all parts of the filesystem,
mounted via dazukofs, are included.

ArchiveMaxSize, ArchiveMaxRecursion and ArchiveMaxRatio. This is
activated by default in order to maintain the highest security:
ArchiveScan yes
MailboxScan Scanning mailbox containers on-access:
If ArchiveScan is set to yes, AntiVir Guard scans mailboxes on-access, when the
following option is active:
MailboxScan yes
This is active by default.
ArchiveMax
Size
Maximum archive size:
This option limits the scanning process to the files with unpacked size smaller than the
specified value (in bytes, KB, MB, GB). The zero value means no limit. The default setting
is 1 Gigabyte:
ArchiveMaxSize 1GB
ArchiveMax
Recursion
Maximum recursion level:
When scanning recursive archives, the level of recursion can be limited. The zero value
means all archives are completely unpacked, regardless of their recursion level. Default:
ArchiveMaxRecursion 20
Archive
MaxRatio
Maximum compression rate for archives:
This option limits the scanning to files which do not exceed a certain compression level. It
ensures protection against so-called "mail bombs", which occupy an unexpectedly large
amount of memory when decompressed. The zero value means all archives are completely
decompressed, regardless of their compression rate. Default:
ArchiveMaxRatio 150
Archive
MaxCount
Number of files in an archive:
The archive scanning is limited to a given number of files within a recursion level. The
zero value means no limit is set. Default:
ArchiveMaxCount 0
External
Program
Starting External Programs When Suspicious Files Are Found:
AntiVir Guard can start an external program when a virus or an unwanted program is
found. This can send a notification or perform an action using AntiVir Guard options.
It is possible to send an SMS, to call the appointed responsible person, to show a dialog
window on the local screen or on another computer, to save the data in another format or
another file.
You can use macros (preceded by %) to pass the results as arguments to the external
program. Thus the data can be treated differently and adjusted to the local conditions.
The following table shows the supported macros and their significance:
In order to use the following program function, you need Dazuko
2.0.0 or higher on your system.
Please use this feature with extreme caution! Check your external
programs for correctness and keep in mind, that an attacker might
use crafted file names (containing spaces, commands, etc.) for
injecting arguments into your external program.

EmailTo Email messages:
AntiVir Guard can send emails, when it detects viruses or unwanted programs. There is
no default setting. You must setup your mail daemon and specify a recipient in order to
send emails:
EmailTo root@localhost
Suppress
Notification

Filtering email notifications as required:
This option can exclude certain messages, when notifications are sent, according to their
priority level. The recipients will only receive notifications with the selected priority or
higher.
Syntax:
SuppressNotificationBelow scanner <level>
The possible priority levels (in ascending order) are notice, information,
warning, error and alert.
Example:
SuppressNotificationBelow scanner warning
Option Function
%h Path to file (may contain special characters)
%f Filename only (may contain special characters)
%p Full path and filename (such as %h/%f), may contain special
characters
%U UID of file (owner identifier )
%G GID of file (UNIX group identifier)
%s File size
%m File access mode (octal)
%De Event type
%DF File system or partition (device) on which the file is located
(hexadecimal)
%Dp PID of the process
%Du UID of the process
%Df Flag of file operation (hexadecimal)
%Dm Access mode of file operation (hexadecimal)
%Sn Name of the detected virus / unwanted program
%Sa Extra information about the alert (if available)
%SU Alert URL.
Some of these parameters are not checked by AntiVir but are taken
from the file properties and forwarded to the running process, so
they must be checked before further processing.
