My computers not all that old its like 6 months if that i dont have all that much installed on it but yet its still running slow expecually my internet we have high speed(Road Runner) I run defrag and disk clean alot to keep it up but its just not enought anyone got any ideas? Im not looking to speed money so free would be nice if i have to i will buy something.

i caught a virus bought a week ago. it got so bad i had to delete the whole partition and reinstall windows xp. now my pc is going extremely slow. all my memory is there and the virus protector doesn’t see any viruses and the registry is fine. so why is it going so slow still and how can i speed it up? im on a low budget
