Insisted my windows system was corrupted. Told him it's off and has been for 2 years. He said turn it on and he'll fix it. I laughed and said why I don't use it. He got mad and hung up on me. I was prepared to go a little longer because he was getting pissed.
Scam. Someone saying a friend has said a computer is corrupted. I assume they are willing to help and once in they lock the computer and charge to unlock. I hung up as soon as I heard the scam. This may be routed call from outside north America.
