Are you on dial up ? or broadband, if dial up I would suggest unpluging your modem cable before continuing.

1st things 1st, run 2 or 3 virus scanners, i would reccommend norton 2005, avg 6 or 7, and mcafee 8, then, run ad aware and spybot, and then, clean boot your system (i can tell you how to do that if needed)
