The directory for clamav signatures has recently changed. If you are unable to start clamav or are getting an error after running aum -uf or awp -s -f, the directory for the signatures may be incorrect.
In the CLI, open
/var/awp/etc/config
Verify that CLAMAV_DatabaseDirector is set to
"/var/lib/clamav"
If it is not, change the directory to "/var/lib/clamav" and then run awp -s -f to apply the changes.
Once the directory is correct, clamd should start automatically or you can start manually with
systemctl start clamd
