AVG and Avast provide in my time zone good updates. Antivir is problematic. Antivir Premium uses to get the best results in tests. So with an up to date database I think it is safe to say that even Antivir FREE provides the best free protection. Problem is Antivir only updates every three days at the best, because their servers are to busy. I removed Avira 8 and changed it for Avast 4.8: with the following underlying idea: Avast up to date provides better protection than Avira with an data base of two or three days old. Reason to choose Avast over AVG is plain lazyness. On the gaming PC my son preferes Avast over AVG (faster?). Same is simpler Opinions ?
