Received call on home landline showing Louisville, KY and this number with a Louisville area code.  The caller was a woman with Indian accent claiming to be from Microsoft.  She asked if I was the owner of the phone she was calling, then told me they were showing I had a problem with my computer and she'd help me fix it.  I hung up at that point.  Others who have received similar calls say that they are asked for email addressees, credit card #s, etc.
