I just got a call from them.  Same guy with thick accent telling me that my computer had downloaded something from visiting a website.  I asked him which computer.  We spared for a little bit and I told him that how was I supposed to know that he wasn't a scammer,  He wanted me to get on my computer and go to a specific file.  I let him know that I would have my local tech support look at the computer and I didn't need his help.
