This number called but left no message.  Caller id was just the phone number.

Caller stated that they were with Windows, and calling about a problem with my computer. I have received similar calls before , and I am quite certain that NO Windows employee is calling my home phone because of a problem with my computer

Caller claimed to be from Spring Technologies in Tuscon and our computer was downloading malware.
When asked what software was reporting malware he stated Windows.  When asked which windows OS he seemed confused.  At this point I demanded identification. Did not give I.D or company address and hung up.
Same guy called a minute later.  When pressed on who he was, his I.D., Company location, he informed me I was full of sh-t and then hung up.  Repeated calls back to number were not answered.  Simple phone search locates him in Marietta Georgia.

This number called saying they were from Windows and needed to discuss my account with me. 770-106-6694
