Although it's not causing any problems with the effectiveness of Avast!, the fact that it's gone on for a couple of weeks without being fixed does make one wonder if (a) the Avast! programmers don't know what's causing it/don't know how to fix it or (b) they don't care. It has to be one or the other. For the first time since I started using Avast!, it's made me think perhaps I should look at other AVs, like Avira, AVG, etc. And that won't affect just my computers. I provide tech support to 7 families with multiple computers, and installed Avast! on all of them. If I switch to something else, I'll also put that 'something else' on all of their computers.
