I told them I have NIS 2012 and Malwarebytes(free) and he said he didn't know my e-mail address and was calling me to help me check my computer for malware, due to the rash of trojans infecting Windows, He was vague about where he was from(some company I've never heard of) but had a Indian accent (which was o.k ) and just wanted to help me check , he was stalling in telling me what to do, I hung up on him............Best Gorpy1
