At least you are honest, Just download a free antivirus, I suggest AVG, ans scan your computer. You should to avoid this int he future patch your windows ( updates) and get a firewall to protect you from the net, and stop using Internet explorer and use firefox or opera. If you cant install avg for some reasons, download Antivir, then reboot and choose safe mode, unzip antivir and scan your computer, Antivir is one of the few anti-virus that can run in safe mode. (safe mode allow you to bypass many trojans and virus, it give you a more basic windows.) PS: if you want to have more help you should post according to the rules of this forum.
