Do not re-format drive some trojans embed in hard drive...the best anti is panda platinum (www.panda.com) its cheap and will kick ass...i use panda+spybot+adaware as they are all compatable with one another and each are better at one thing or the other ...you can also get spyblaster to work alongside the above..this is available through the spybot site...only other/best solution is to replace hard-drive
