For Online Computer Support, Ask a Computer Technician
Hi, I'mCustomer Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP.
I am sorry this has happened to you. This is a popular scam that has been going on. Microsoft does not call customers regarding issues with computers, Please do not let them have access to your computer anymore, as they can install spywares and other malicious items. Report them to the Internet Crime Bureau here - http://www.ic3.gov/default.aspx
Let me know if you need further assistance
Do you still need help please?
