This thread is way above my pay grade.
However, I posted earlier that I got the BSOD on TWO different VISTA computers. I never had it before the 6 upgrade; and never had it again when I removed Avast and replaced it with AVG.
I have the same BSOD on an XP laptop but expect that to go away when Avast does.
As previously stated, because I've loaded the same programs on my 3 computers, I'm convinced that one of them conflicts with Avast.
