I have Norton Anti-virus and I update it regularly. However whenever I perform a full system scan, it never finds anything other than a cookie or two, so I don’t see the point. I regularly delete all my browsers’ caches, files, cookies, etc, so I don’t see the need for the virus protection other than needing something to automatically start and slow my computer down when I don’t want it to.

Question I guess is, do I actually need the virus protection?
