I've had Norton for years but they're starting to piss me off. My subscription has expired but I notice when I click on renew it takes me to their website and a renewal costs $39.99. But if I simply do a search for antivirus programs, I can dowload the entire new 2009 Norton antivirus for ten bucks less. Why are these people trying to gouge existing customers and not new customers? It pisses me off. It's just enough for me to never use Norton again. So what antivirus do you use and why?
