Yeah, I had a guy calling me saying the same thing - that he was authorized by Microsoft to call people who's PC's were being misused and he said, someone was stealing my IP address for Cybercrime. He wanted me to follow his instructions to type something in which allowed him to get a report and block the mis-use. He sounded fake, I asked for his name & no. ..... He gave me this no. (07) 3102 5705 & said his name is Alex Wilson (he had a very thick Indian accent!!). I told my friends about this and they say it's a scam
