i love it how people dont give two stuffs about OP and just had to post because someone posted something controversial
stay classy forums
woah man no need to get hostile over people reacting
anyways op id suggest mbam but judging by the fact whatever you got was taking up system usage its probably that
i had a problem with avast and it used up 99% of my usage but it eventually went away, so it might be avast itself more than anything
also what did you download? some video file?
