Yeah, this is a scam Microsoft will never call you and tell you there is a problem with your computer. They get you to use the run command which is the same as using the input line in the browser they take you to one of their websites that may install malware on your computer. These guys don't like me cause I mess with them. The one thing good about them is they gave me a realtime test that showed me what they could see. They can only see what you let them see. Never run the computer with the Icons showing they can only see the desktop when they are.
