Personally having used Nortons Internet Security 2004 for over 6month solid with heavy use of my pc systems, I noticed that it was taking ages to load and was having more issues with the ccap.exe problem. I then changed on advice of a friend to Avast! Home, and Sygate Personal Firewall with the two running they take much less resources from my pc and are much more stable the best thing of all though, is that they are free
highly recommened by myself as AVG Just forced users onto 7.0 and upto the best of my knowledge they have not released the upcoming free version to the public.
