avast and grisoft (AVG) are 2 of the best virus protectors around. I am a fan of avast myself. Norton is just getting to expensive. I think if you buy it one time you shouldn't have to buy another one or pay for an update next year around. I mean honestly. you spend over 40 dollars for the program and then every yeat you have to pay an additional 40 dollars just to keep it up to date. forget that.
