ClamAV

ClamAV is an antivirus. It is composed of three components: a daemon that can run scans, a client to run scans with the daemon, and an updater(freshclam) to make sure you always have the latest virus definitions.

• apt install clamav-daemon clamav clamav-freshclam
• Make sure that the updater service is enabled and started:
  • systemctl status clamav-freshclam.service
  • If not, enable and start it: systemctl enable clamav-freshclam.service && systemctl start clamav-freshclam.service

The first freshclam update will take a bit of time, subsequent updates are incremental and thus will take less time. You can check the update log with journalctl -u clamav-freshclam.service.

Running a scan

With the command line:

• Generally, clamscan {file} should work, see man clamscan for more options.

With a GUI:

• apt install clamtk
• Note that when you run a scan the progress bar windows may seems like it's stuck, but it is actually scanning.
