Norton is a virus within itself. I had nothing but problems out of it a few years back. McAfee is just as bad so stay away from it also. In Louisville we have Insight BB. If you have Norton it just screws up everything with Insight BB. You basically can't even use your CPU. So I got rid of it and now have CA. Not sure where to get it, Insight offered it too me and set it up. Not had a problem since.
