Then I got suspicious...
I then booted into Slackware and ran clamscan on my Windows partition at /dev/hda1. Sure enough, there was a virus there! Clamav detected it, and it didn't cost me a penny like with Norton, McAffee et al. If you have a Linux partition on your hard drive but mainly use Windows, clamav will save you a lot of headaches and money if you suspect your Windows has a virus. I highly recommend it!
