Just received a call from someone that I barely understood (ON MY CELL) that said he was from Microsoft.  Said they had been receiving reports "from my computer".  I didn't hang on long enough to hear his ultimate goal.

I got this scam but rather than calling me, they froze my computer with a blue error message screen on my computer. To call the 800 number and speak to an Microsoft representative. Bogus!!! Scammers just the same. The number was 1800-477-1412. If you have this error message, call your IT or virus protection company., they will help you through it. don't fall prey to that, they play on your fears and are excellent manipulators to make you surrender your info.

Received call from this number today, but I didn't answer and they did not leave message
