Clear out your temp folders first (what O/S, btw?)

Run Adaware and Spybot to catch any mal-ware.

Running a virus scan wouldn't be a bad idea, either. If you don't have any virus protection software, try AVG from www.grisoft.com

If don't have one already, it may be a good time to put up a firewall. Sygate is a good free one.

Hope this helps ;)

force flow pretty much hit the nail on the head. I personally use ZA freeware as a firewall. Run swat it too to check for trojans.
