This number is listed for a dentist in San Carlos, CA. When I call back it's a fax line. On the 3rd time I picked up,
thinking it was a legitimate call from the dentist office only to hear the familiar spam spiel regarding problems with my computer.
Called with a claim that there was an issue with my computer... which is amazing since I haven't had a computer in almost 2 years. He spoke in a very thick Indian accent and I told him he should be ashamed of what he was doing. I asked if his mother knew that he was scamming people, but he dodged the question. *shocked /sarc
These calls are from a computer repair site calming to be Microsoft repair specialists. They are not. They just want you to fall for their line and get access to your computer. It is best to just hang up on them. They have been reported to Microsoft.
