Same thing as everyone else here states. Fake screen lock and pop up telling me to call a number. I did not. However, I did go on line using my phone and found a company that was Microsoft, or so I thought. It was not, but they insisted they were an authorized service dealer for them. After an hour of trying to sell me a service pack for a year or two for huge dollars, I told them not interested so they finally reduced it to 109.95 for a one time fix. Scary letting them take over my computer. Now, I find that this very fake virus is going around and is not a virus at all. People, simply his 'ctrl, alt, del' and you're in business. I keep checking to see that they are not back in my computer via firewall and so far, not. They are a big scam money making business and need to be taken down. I told them that they may well be the very people who initiated this fake virus so that we all call them. Stay far away from these con artists.
