The number on my ID was the same as the other posters here except the area code was 435. A man with an Indian accent said he was with Windows and they were getting signals from my computer that it was malfunctioning, etc. I had gotten a call like this before, so I just told him he was a scam and hung up.
I have heard of others playing along with this type of thing, putting the caller on the spot by asking him to ID their computer system, etc. One would-be victim pretended to make the changes to his computer specified by the caller, then pretended the computer had crashed, threatened to call police, etc.
Anyway, I got the following info from People Search about this number: it's a land line, carrier Eschelon Telecom, Inc. in Park City, Utah.
