I was tired of the Norton nagware, and wanted something less bloated that wasn't such a resource hog. I was considering McAfee, but I read that it's just as annoying as Norton, and then I discovered Avast! (Home Edition). Believe it or not, it's free, and rivals the big guys. I've had it about a month and love it. You do have to register it within 60 days, but it's still free.
