Open-source antivirus toolkit.

Installation on Fedora

sudo dnf install clamav clamav-update 

List all the services you can start:

$ ls -al /usr/lib/systemd/system/clam*
-rw-r--r--. 1 root root 519 Feb 20 16:50 /usr/lib/systemd/system/clamav-clamonacc.service
-rw-r--r--. 1 root root 389 Feb 20 16:50 /usr/lib/systemd/system/clamav-freshclam.service
-rw-r--r--. 1 root root 398 Feb 20 16:44 /usr/lib/systemd/system/clamd@.service
lrwxrwxrwx. 1 root root  24 Feb 20 16:50 /usr/lib/systemd/system/clamonacc.service -> clamav-clamonacc.service


Before you can start the ClamAV scanning engine (using either clamd or clamscan), you must first have ClamAV Virus Database (.cvd) file(s) installed in the appropriate location on your system.

sudo freshclam

Then start ClamAV services:

sudo systemctl enable clamav-freshclam
sudo systemctl start clamav-freshclam
sudo systemctl enable clamav-daemon
sudo systemctl start clamav-daemon


sudo clamscan -r /home
