I consider cookies a form of spyware because after a while, and left to their own doings, they will choke up your surfing experience.

Then you have been invaded by insidious worms of programs that crawl and leave their dirty digital footprints all over the place. Get an anti spyware program! Get an antivirus! It will do you good!My last piece of advice to you is to get a good registry cleaner and optimiser. I will akin the registry to a matrix of elevators in an extremely busy office complex.
