I have an old computer that was given to me. When I got it it was all cleared out. I used it with my Blackberry and the Tether app to get online to load caches onto my GPS. I think there might be a virus on it, and it's also very slow. I stopped using it when I got my Android. Is there a way I can wipe the comouter completely and start new, while getting rid of any virus or key logging things? Thanks. If not, I am going to get rid of it.
