How the Linux Antivirus works?

The output format of virus scan
Every malicious file detected is reported on a separate line. The clean files have an “[OK]” string. The infected files that could not be scanned because of insufficient permissions or corrupted archives will have an “[ERROR]” string. Files that were excluded from the scan using the -e option have an “[EXCLUDED]” string.

Virus definitions update
Regularly updating the virus definitions database (VPS) is necessary to keep your antivirus protection up to date. Avast Business Antivirus for Linux provides a shell script which checks for, downloads, and installs the latest VPS. The updated script is installed by default and executed every hour as a cron job.

Streaming updates
If enabled, the scan service establishes a permanent network connection to the Avast cloud and retrieves virus definition updates as soon as they are released. Streaming updates complement the regular virus database updates so you are always protected.

Distribution packages
The Linux antivirus software components include DEB for Debian (Ubuntu) systems and RPM for RedHat/SUSE systems, which are distributed as standard software packages.. Software repositories are also provided so that all of the standard system management tools can be used to keep the Avast Business programs up to date.
