For someone with such a mess with malware and probably virus infection, going on-line isn't recommended. Why not take a CD with a bunch of useful utilities, which you can download or use copies that you have recently (these will be more up to date). avast! (boot scan if OS allows), AdAware, Spybot S&D, HiJackThis, Eddy's HJT Analyser, these would be a good start.
