Do I have a virus?

Episode 995 (1:30:22)

James from Encinitas, CA

James' neighbor used a speed up utility on his computer and now it runs really slow and behaves strangely. Leo says there's a very good chance the program his friend used had viruses in it. He then got a call from "Microsoft Support Services" to clean off his computer, and he let them. Leo says that's a scam and he got bit a second time! The worst part is, he probably got charged for it! At this point, the only thing James can do is backup his data, format his hard drive, and reinstall Windows from a known good source. Then he should update it, and never let them do that again.
