Welcome to the forums.
I think many users don't take the time to get to know the programs that they use (not just avast), a little time spent reading help files (RTFM, F=flipping), etc. gets the most from the program, most efficient/effective settings, etc.
For most it's when they experience a problem that they start to get religion, and RTFM. Then it's panic stations, as this saying goes 'when you are up to your ar*e in alligators, the last thing on your mind is draining the swamp.'
Time spent in reconnaissance is seldom wasted, get to know your software.
