Avira GmbH Avira AntiVir Server/ Professional (UNIX) 44
6Updates
With Avira Updater you can update Avira software on your computers, using Avira update 
servers. The program can be configured either by editing the configuration file (see 4.1.4 
Configuration of Avira Updater in avupdate-guard.conf), or by using parameters in the 
command line.
It is recommended to run the Updater as root. If the Updater does not run as root, it does 
not have the necessary rights to restart AntiVir daemons, so the restart has to be made 
manually, as root.
Advantage: any running processes of AntiVir daemons (such as Scanner, AntiVir Guard) 
are automatically updated with the current antivirus files, without interrupting the 
running scan processes. It is thus ensured that all files are scanned.

Automatic updates with cron daemon
