I had been getting calls from this number a month or so ago. One day I actually answered. It is some person who says your computer is causing a problem and you need to stop. The person who had a thick accent-either middle eastern or perhaps India-says they have information on my security certificate for my computer and they can shut it down if they want. I said prove it and they said they didn't have to. I told them they are liars and if this was true they should send something. They said they didn't have to do that. I asked others and it is a scam. I am getting calls all over again from the same number.
