LOL This has been going on for a while. We used to get these calls once a week. Often the english the person on the phone was speaking was so broken that I hung up immediately. However I was online when the call came in. I looked online while they were talking and when they finished I told them that it was impossible that my computer had a virus like they were speaking of, that Microsoft does not contact people in their homes as a policy. And that their scam is already posted on the internet so if they called again they would be hearing from my lawyer. And the proper authorites would be contacted.
They apologized and hung up, havent heard from them since.
