I got a window page come up that says this site says "dear customer, your system has detected possible suspicious activity. Pls call the toll free number below for a microsoft certified technician to help you resolve the issues 888-978 0105.
And the rest says something about not shutting down and closing the browser b/c it may cause corruption. the message was accompanied by loud sound like a code red alert. the computer froze. I ended up manually shutting it down and when I
opened the browser again, it was still that way.. ended up deleting cookies and history a few times before it went away.. just wanted to know if that is a legit notice that Microsoft sends out.. I didn't want to call that number b/c I couldn't verify the source.
