I just got a call from this "Name Not Found" number and could tell it was a call center so I didn't say anything and they hung up. If you or someone you know has been suckered or near suckered by this scam, go ahead and file a complaint with the FTC. The Complaint Assistant is here:

At 3:25 pm July 20th 2012 Received a call from 9145678923 from a person speaking with a strong foreign accent, I could not understand much of what he said, except something about my computer. I told him I could not understand him and was hanging up, and I did.
Received a call from a man speaking with a thick indian accent. He was saying something about my computer. It sounded as if he was calling from a street corner. I hung up on him. He then called back 20 minutes later. I hung up again.
I tool received a call from this number.....said he was calling from some Stadium and there was quite a bit of noise in the back ground. He actually knew my first name and said his name was Alex. He pretended that he couldn't hear/understand me and after about 30 seconds, I hung up on him.
