Core Scanner
An on-demand antivirus scanning service with a command-line utility for Linux that integrates with AMaViS email servers. Clients connect to the service's UNIX socket to perform core and command line utility scans and receive immediate scan results.

File Server Shield
A real-time file scanner that scans files written to any of the monitored mount points. Supports fanotify-based "on-write" file system protection designed for use on file servers, efficiently protecting your files on both Samba and NFS.

How does Linux Antivirus work?

The output format of the virus scan
Each detected malicious file is reported on a separate line. The clean files have an "[OK]" line. The infected files that could not be scanned due to insufficient permissions or corrupted archives have an "[ERROR]" string. Files excluded from scanning with the -e option have an "[EXCLUDED]" string.

Updating virus definitions
A regular update of the virus definition database (VPS) is necessary to keep your antivirus protection up to date. Avast Business Antivirus for Linux provides a shell script that checks for, downloads, and installs the latest VPS. The updated script is installed by default and run as a cron job every hour.

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

Distribution packages
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 standard system management tools can be used to keep Avast Business programs up to date.
