To update signatures manually, run the following: This will regularly update the unofficial signatures based on the configuration files in the directory /etc/clamav-unofficial-sigs. # sudo -u clamav /usr/bin/fangfrisch -conf /etc/fangfrisch/nf initdb Most importantly, Fangfrisch never needs to be run with root permissions, unlike clamav-unofficial-sigs.

Option #1: Set up Fangfrischįangfrisch was designed as a more secure, flexible and convenient replacement for clamav-unofficial-sigs, and requires very little configuration. Note: You still must have the rvice started in order to have official signature updates from ClamAV mirrors. MalwarePatrol, SecuriteInfo, Yara, Linux Malware Detect, etc. Both will add signatures/databases from popular providers, e.g.

To add the most important ones in a single step, install either clamav-unofficial-sigs AUR (see GitHub description) or python-fangfrisch AUR (see online documentation). Otherwise read the Troubleshooting part or ask for help in the Arch Forums.Īdding more databases/signatures repositoriesĬlamAV can use databases/signature from other repositories or security vendors. In order to make sure ClamAV and the definitions are installed correctly, scan the EICAR test file (a harmless signature with no virus code) with clamscan.

The daemon is not needed if you only want to perform stand-alone scans.

You will need to run freshclam before starting the service for the first time or you will run into trouble/errors which will prevent ClamAV from starting correctly.

Start/enable rvice so that the virus definitions are kept recent. If you are behind a proxy, edit /etc/clamav/nf and update HTTPProxyServer, HTTPProxyPort, HTTPProxyUsername and HTTPProxyPassword.

Now how to automate that or script a clean way to do that? That is out of the scope of your question. Then just restart the ClamAV service like this: sudo service clamav-daemon restart Those files should then be placed in the /var/lib/clamav/ directory of VM 1 and transferred over to VM 2 to place in the same directory there.

To download those files from the command line you can run these Curl commands: If you cannot use sudo freshclam for some reason, you can get the updated databases directly from the official ClamAV download page at these URLs: Method 2: Direct download of the ClamAV database files. Again you have to restart the ClamAV daemon on VM 2 after that is done. So at this point, you can copy the files from the VM 1 /var/lib/clamav/ directory over to VM 2 to place in the same directory there. That said, sometimes you need to restart the ClamAV daemon each time the DBs are updated so run this command: sudo freshclam & sudo service clamav-daemon restartĮither way, your ClamAV database files should be updated in the /var/lib/clamav/ directory at this point. Just run that command and the ClamAV databases should be updated. This is the command you can use on VM 1 to have it update files: sudo freshclam That said there are two ways to get updated ClamAV files. The download URL it recommends using is dead and the core of the instructions seem to be about putting the files on a USB flash drive. The problem is that guide you link to is from 2009.
