Was I the victim of a computer scam?

Terry responded to a pop-up from someone who used remote access to get into his computer. Leo says that is a complete scam and it's likely that a they've infected his computer with viruses and maybe even key loggers to monitor activity on the computer. They even tried to charge him for this. Leo advises that he talk to a computer store in his area. Then have them backup his data and reinstall Windows. He can run a scanner such as the Microsoft Malicious Software Removal Tool by clicking Start, selecting "Run", typing MRT and hitting enter.
