Just in case you weren't aware, Microsoft announced a bunch of vulnerabilities late last week. We all know this is nothing new... :P

However, the recent announcements included some particularly nasty vulnerabilities (MS05-039), and there is already exploit code kicking around the net. I'd STRONGLY recommend applying the latest windows updates if you haven't already done so, and make sure your antivirus is always up to date.
