Using Kaspersky Anti-Virus 21
We strongly recommend that you set up the keepup2date component to
update the databases every hour!
After a successful update, a command specified as the value of the
PostUpdateCmd parameter in the [updater.options] section of the
configuration file will be executed. By default, this command will automatically
initiate reloading of the anti-virus databases. Incorrect modification of that
parameter may prevent the application from using the updated databases or
cause it to function erroneously.
All settings of the keepup2date component are stored in the [updater.*]
sections of the configuration file.
If your network has a complicated structure, we recommend that you download
updates from Kaspersky Lab’s update servers every hour and place them in a
network directory. To keep other networked computers constantly updated,
configure the local computers to copy the updates from that directory. For
detailed instructions on creation of a public directory, see section 4.1.3 on p. 23.
The updating process can be scheduled to run automatically using the cron
utility (see section 4.1.1 on p. 21) or started manually from the command line
(see section 4.1.2 on p. 22). Starting the keepup2date component requires root
or kluser user privileges.
4.1.1. Automatic updating of the anti-virus
databases
You can schedule regular automatic updates for the anti-virus databases using
the cron service. You can configure cron either manually or using the
keepup2date.sh script located in the /opt/kav/5.5/kav4proxy/setup/ directory.
In order to create a сron task updating the anti-virus databases every hour, enter
the following in the command line:
# /opt/kav/5.5/kav4proxy/setup/keepup2date.sh –install
To delete the cron task for hourly updating of the anti-virus databases, enter the
following in the command line:
# /opt/kav/5.5/kav4proxy/setup/keepup2date.sh –uninstall
