Oh the system is most definately clean. What I think happened was during the cleaning, I deleted a key I was not supposed to. Nortons works just fine now, as does everything else. I also used Hijackthis, and think I might have deleted it via that program, and the backups folder is empty.
What I really need help with is how to add it back. Because the registry is very big, and something I am not entirely comfortable with yet when it comes to adding entries. I really would not know how to set the value.
