I just received a call from California, 408-023-6901, saying they were from regarding microsoft windows having some problem. I asked for a little more info, and he started asking to verify info about my computer, which I refused to answer, and said if there were a problem I would expect an email regarding this, and, unfortunately, I started to raise my voice, and he hung up. Has anyone else gotten a call like this, and reported it to anyone? Any other info? Thanks.
