How The Anti-Virus Scam Works
The anti-virus scam starts when someone calls you and offers to provide computer anti-virus services, or when you respond to a “pop-up” anti-virus advertisement on the Internet.
In either case, the scammer is not selling a real product, but trying to gain remote access to your computer and to get your credit card information. The scammer will say they need remote access to provide the supposed services, and will ask for your computer passwords and related information. They will also ask for your credit card information, so they can bill you for the supposed services. The exact details of the scam can vary.
