So, given what you know about my system, in my current state, would you recommend reformatting and reinstalling WinXP? And also, is it frequent for a malware to be stealthy to almost all known antimalware programs (Nod32, Kasperski, Norton, Lavasoft, Spybot, Spyware Doctor, Spysweeper,etc etc)?? If so, then from the moment you connect to the internet, and no matter how many antimalware software you might use, there's always a chance of being infected without knowing.. :(
