Im using Deep Freeze., The Ultimate System Restore. It freezes your baseline configuration & prevent any changes to your registry & drivers & windows. It can destroy any viruses even the metamorphic viruses(the most powerful virus) which some can evade detection by all virus scanners because of their ability to transform completely. It concept is the "end of time". No viruses, trojans, worms, spyware, rootkits, dialers, jokes, hacktools, can beat TIME itself. Just one reboot all mallware totally destroyed 100% like no mallware has infected you. !!!!!
