I received a call from them stating that they were from Microsoft Windows and I almost gave them a check or credit card and I'm glad I hung up on them before that happened
This is a scam to get access to your computer. They say they are getting errors from your machine and want you to allow access to it so they can fix it. These folks called a relative of mine and told him the same thing. Funny thing is he has no computer whatsoever. Don't fall for it..even though they claim to be Microsoft.
On 3/28/15 I received a call from this number. When I answered, they hung up. I researched it and found it was someone trying to get access to credit card accounts.
