WHAT HAPPEND MY COMPUTER IS INFECTED AND I DONT WANT TO PAY FOR ANTIVIRUS PROGRAMS?

turn off the computer, turn it on, *** soon as your computer brand logo shows press F8 alot, until a black screen comes up with options, choose safe mode with networking... open internet explore, go to superantispyware.com, download the pro trial version , scan it and clean it in safe mode, then restart it in normal mode, rescan it again, most of the viruses should be gone in safemode but just rescan it again in normal mode to make sure... hope it helps!!!!!!!!!!!!
