This number just called me also and I did not answer it and glad I didn't because I had a computer scam call like this one last Fall. Beware of these scammers!!!
He claimed to be a Microsoft technician, and seemd to have a French accent. Apparently my computer was hacked, or need protection from hackers, or I had an illegal version if software and would stop working tomorrow and he was trying to help me. The story kept changing. He didn't know what version of software I had, or how many computers I oen. It sounded like a business center with lots of neighboring workers. First tried to get be using the run command, I acted stupid, and then tried to get me to ammyy.com. That's when I hung up.
I received a call from this number about 2 months ago around or just after 7pm. Said I have a problem with my computer and he was from Microsoft. I hung up.
Got a call about 2 minutes ago, and there was nothing at the other end. I hung up, call the number, and was told there was trouble routing the call so could not be connected. BS...something must be able to stop these hackers from calling!
