I tried the boot scan of all drives, which ran fine. I then tried the quick scan again, and Avast 6.0 crashed in aswsp.sys - stop 0000008E. I read about others crashing there too, and an Avast support person saying they have a program bug. I will see about updating to the program, but I just installed the most current version from Avast just last night.
So I doubt there is any newer ones.
