The FBI is warning computer users that they might lose Internet access next week if their computer is carrying a virus that was spread by a fraud ring and dismantled last year.Back in November, the FBI set up temporary clean servers for those affected by the virus, but they're cutting that service off on Monday (July 9th). An estimated 45,619 computers in the U.S. are still infected, down from an estimated peak of 175,365.To see if you're infected and to learn how to strip your computer of the virus, visit www.dcwg.org.
