If you are a Windows 2000 or XP user, take a close look, here I will teach you a trick called "Golden Cicada shedding its shell" - and with just this trick, you can defeat all viruses! If you have a newly installed system (or if you can confirm that your system is currently virus-free), that's even better. Now, immediately open: "Start → Programs → Administrative Tools → Computer Management → Local Users and Groups → Users"!
