personally i would stick with Avast, its not as heavy on your system - though i dont know PCTools that well. but whichever one you chose, remember to keep it updated.
I also purchased PcTools Internet Security for 3 computers. Would it be any better than avast, or should I stay with Avast? On other computers that I have should I use Avast instead of PcTools?
i dont think there would be any from my final post? if you are referring to the prior posts where we were trying to get combofix etc running then i dont need to see them.
Do you want to see the final combofix or otl logs?
