This number called me today 5/22/14 at my work, Caller ID says Zombo, D C. They are stating that my computer has malicious software and needs to be cleaned by them, since they are from 'Microsoft.' They are scammers who hack into your computer and steal your information. He had an Indian accent the [***] people or whatever. Do not fall for it, when they call, have them go through their entire speech and when their done, just tell them you have a bad connection and have them repeat everything again. make up a new excuse the next time and have them repeat everything again. You're Welcome.
