I've got a nasty problem that I'm sure is malware. Spybot has made a huge improvement overall, but Chrome still experiences sudden dramatic slowdowns, especially in scrolling through a page - so bad it's unusable - and displaying videos. I have no scrolling or video problems in IE (which I hate having to resort to). However, Spybot isn't finding any more malware. The problem isn't as severe as it was, but it isn't going away.

Does anyone have suggestions or ideas?
