Norton's used to be a good program but isn't any longer. We had Norton's and have had a major problem with a virus just this past week. Had to take our brand new computer in to get rid of it. They recommended Kaspersky's virus protection. I had never heard of it before, but apparently it's very good. Apparently, Norton's posted some information on their site about their coding which allowed hackers to get by their virus protection. Not good at all. $160 later and our computer is still acting "funny."
