|Not an expert but running two AV programs at once is usually not suggested.|
I hate AVG's updater that runs on every startup, it's slow. I swear it's logging into some network in Czechlovakia or something, and the updater program that runs afterwards is very slow.
Avira has been good for me, but missed a serious bug on a computer and I'm not sure what it was, or why it missed.
Sorry, not much help. I mean it's freeware right?
