Occasionally i need this notes for ClamAV and I'm searching around to find some commands and locations, so I decided to write them here, in case I want to find them in the future, or maybe someone else needs them.
clamAV databases folder: /var/lib/clamav/
stop freshclam: sudo /etc/init.d/clamav-freshclam stop
update databases: sudo freshclam -v
freshclam.conf location: /etc/clamav/
