That's real shoddy. Avast! is big enough for them to be known and travel by word without these pop-ups.
Some users, like me, don't have the money (or the need/want) for features further than what the free version offers. That alone, is why I highly suggest changes be made to allow these turned off (without the turning off of all/the useful ones).
I'll stick around for now, I guess. But one thing I can say is that I will not be suggesting Avast! to other people anymore.
