Installing AntiVir (example for AntiVir Server)
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 without
AntiVir Guard. AntiVir Guard can be easily installed later. For more details,
see See The Dazuko Kernel Module.
* Type the command:
Please note the dot and slash in the command syntax. Typing the command without
this path specification, leads to another command, which is not related to
AntiVir installation process and this would result in error messages and
Press q to close the license text view.
The installation script starts. After you agree with the license terms, it will
copy the program files. The Installer can read an existing license key:
Do you agree to the license terms? [n] y

2) Configuring updates
An internet updater is available…
Would you like to create a link in /usr/sbin for avupdate-guard? [y]
* Type y and confirm with Enter .
Then the script can create a cron task for automatic updates:
linking /usr/sbin/avupdate-guard … done
Would you like to setup Scanner update as cron task ? [y]
The update cron job uses the minute when the product was installed. If you
want another update time, you can change the entries later, in
* Press Enter . You can change this setting later.
Then select the update interval (daily – d; every two hours – 2):
Please specify the interval to check.
Recommended values are daily or 2 hours.
available options: d 
* Enter d or 2 .
If you selected daily updates, you can specify the time of the day when the
updates should start:
The AntiVir Updater can be set to always check for updates at a particular time
of day. This is specified in a HH:MM format (where HH is the hour and MM is the
minutes). If you do not have a permanent connection, you may set it to a time
when you are usually online.
available option: HH:MM
What time should updates be done [00:15]?
* Press Enter or set another time first.
Then the installer asks if you want to check for Product updates every week:
Would you like to check for Guard updates once a week ? [n]
* Press y , if you want to create this task, or just press Enter , if you
The next step of the installation process is installing the main program.

linking /usr/lib/AntiVir/guard/libdazuko.so to /usr/lib/AntiVir/guard/
If the attempt to install dazuko fails, you have to compile the module
yourself. For more details, see See The Dazuko Kernel Module.
AntiVir can be installed even without dazuko, but in this case it will run
without AntiVir Guard.
The installer then reads /etc/fstab , to check the directories to be mounted as
dazukofs. If no entry is found, it asks you to enter one directory to be
scanned by the Guard:
Guard will automatically protect all directories
which are mounted upon dazukofs filesystem.
Please specify at least one directory to be protected
by Guard to add in /etc/fstab: [/home]
There are some file systems that should not be overlayed by dazukofs, since
no security gain would be achieved, but on the contrary, it could lead to
system malfunction. Examples of these file systems are sysfs (/sys), procfs
(/proc), usbfs . These file systems do not allow the creation of files
anyway, so they do not need to be protected against malware.
The special directory “/ ” (root ) should not be mounted with dazukofs,
because it may also be the root for other file systems, which likewise should
not be mounted with dazukofs.
Mounting “/ ” could also be dangerous due to the fact that there will very
likely be processes already working on files under/ before dazukofs is
mounted. This might result in undefined file states, if those files are later
accessed through the dazukofs layer.
* Type one directory, which you want to be protected on-access (for example, /
home ) and press Enter .
If you want to modify the list of protected directories, you can add or
remove entries later, by editing /etc/fstab file and remounting dazukofs.
Then the installer checks if the default quarantine directory exists:
/home/quarantine, the AVIRA Guard default quarantine directory, does not exist.
INFO: You can change the quarantine directory in /etc/avira/avguard.conf.
and /etc/avira/avscan.conf after the installation.
Would you like to create /home/quarantine ? [y]
* Type Enter , to create the directory, if necessary. You can change it later
in the configuration files.
Then the script can install a GNOME plug-in, which would allow you to add the
status icon for AntiVir Guard to the panel ( – Guard is active; – Guard is
Would you like to install the AVIRA Guard GNOME plugin? [n]
* Type y and press Enter , if you want to install the plug-in,
or just press Enter , if you don’t.
Then you are asked if you want to create a link to avguard and if the Updater
should be automatically activated at system start:
Would you like to create a link in /usr/sbin for avguard ?[y]
linking /usr/sbin/avguard to /usr/lib/AntiVir/guard/avguard … done
Please specify if boot scripts should be set up.
Set up boot scripts [y]:
* Confirm with Enter .
The automatic system start is configured:
setting up boot script … done
installation of AVIRA Guard complete
Then the script can install the optional plug-in for Avira Security Management
4) activate SMC support
The AntiVir Security Management Center (SMC) requires this feature.
Would you like to activate the SMC support? [y]
* If you are using Avira SMC, type y or confirm with Enter .
The plug-in is installed and the installation process is complete. You can
start AntiVir Guard, if dazuko is correctly compiled:
Would you like to start AVIRA Guard now? [y]
Starting Avira AntiVir Server…
You will see a report that indicates the completion of the installation:

* Finally, you can start AntiVir:
Modified binaries will not run.
