My husbands job is computer repair. Microsoft will never do that. Neither will Apple. That's someone in another country trying to remote access your computer. If someone asks you to look up numbers on your computer, run their programs, or asks you to use "log me in" then they are not reputable unless you were on the actual microsoft webwage itself... and even then they want you to mail your computer in or wait for a technician to come out. I cannot tell you the scams people have gotten themselves into and once they are in your computer... they run a muck! Sometimes there's still traces of it, even after everything is all "fixed". Scary stuff! Do not call that number, and get someone to run a thorough virus removal that takes care of adware, malware, viruses/worms etc.
