650 282 2091. These people call, leave no info, if you call back they want an authorization code, possibly a miss-dial or someone else is "spoofing" their number to coverup their real number.
I don't answer the phone when I don't recognize a number or a name. Caller ID showed "VOIP caller". If the call was legit, a real person's or business name would appear.
The next time you get a call from someone claiming that they are from Microsoft Windows and there is a problem with your computer, tell them you have Andersen Windows ( or whatever brand windows you have in your residence). That will confuse them. I've done it in the past and they stopped calling for many months afterwards.
I also had a thickly accented Indian making believe that he was from iolo, and that my computer infected, but if I opened my computer up to him, he would help me. How did this rat know that I subscribe to iolo?
This is a scam. Do not allow him access to your computer. He wants to install malware, viruses, etc. Their goal is to steal information from you, i.e. banking information.
