The last virus I got was when the Blaster worm first hit the market. The last spyware was a little while after that.
I'm tellin' ya; properly set up router firewall, separate Windows partition, FireFox, NoScript, and AdBlockPlus. Plus, an online-email system like GMail. Nothing gets through unless I want it to.
Because of one of the threads around here (this one?) I just recently started using COMODO for the heck of it. There is a noticeable drop in game performance, but I'll tweak with it. It didn't pick up anything other than false positives during two scans on my four-year-old data, nor did ESET's online scanner or Kasperky(sp?) a while back.
Plus, I'm a teenager. ... *cough*
