Personally have not tried it. I tried AVG for Linux and it was almost a
disaster, It terribly bogged down the system so badly to almost imposiible to
navigate the system to uninstall it. Made me think I was on my old windows pc. I
tried the Esest for Linux trial and was seriously impressed. It literally was
like it was not even running as it has the real time process active.

Mine is only one answer, and there will probably be more and some first hand
experience with Avira for Linux.
