I run all the spyware programs, but they redownload in a day. How do i stop them from coming back. Perfect Nav is one of them and all of a sudden it becomes 5 spy programs and keeps increasing, but i cant seem to find what is downloading them. I have 3 computers that have this problem and i dont know what to do. Spybot helped, but they came back a day or 2 later. I dont want to have to format, all these computers.
