I got that virus that comes up and says you are getting a virus and have to run the anti virus program to stop it. I didn't recognize the anti virus program and wouldn't click on it. It kept coming up so I shut the computer down. The virus got in but I shut down my computer before it could do the worst. My sisters husband is a computer tech and works on just such things as viruses. He took it and fixed it in a few hours. He laughted too when I got upset about it. Those guys just love their work. He said if you get a message like that again or think something is going on turn the computer off before the whole virus can be down loaded. That keeps the amount of damage down.
