You would be surprised how many people are running norton except it is no longer Norton, it has become somthing else, you can usualy figure this quickly since you wont be able to un install it. Norton is the most hacked program of its type. There are so many hacks out there that turn norton into nothing but a big Trojan, sure it still block and removes some threats, all the while some Rusian collage student is monitoring all of your key strokes, and spaning the internet through your machine, which is why a lot of machines with Norton run so slow.
