Received a call from this number from man with a very heavy Indian accent who said my computer was "sending a critical error message to the internet and he needed to help me fix it."   He said he was with Microsoft Corporation.   First off, Microsoft Corporation does not have my cell phone number.  Secondly, when i asked him for my IP address he said he did not have that information.  I hung up.   Obviously he was spoofing the phone number of a New Jersey Dentist.
