I've used Norton a lot, and been fairly happy with it. I'm not happy with it's CPU usage and how much it slows down the computer. My subscription ran out recently, so I'm going to install AVG, I've used it before and I like it. It's definately the best free anti-virus software I've ever used. Anyone here ever used Fix-It utilities? I hear they are pretty good, and they have anti-virus and anti-spyware, well actually they have a full suite much like Norton.
