Do you have the virus definitions in /var/lib/avast/defs? They are downloaded during
the installation, if you are not online at that time, Avast won’t work until you download
them using the /var/lib/avast/Setup/avast.vpsupdate script.
I installed from rpm online.
But It didn’t make /var/lib/avast/defs folder.
I tried different CenOS7.1 server, but the same problem.
Avast Security Suite for linux is support CenOS7.1?
