I asked him if it was for sure my computer and he said 'yes, each computer has a unique ID and I can prove to you that this is a legitimate call' So I said, OK, prove it. He ignored my request and asked me to login. They will lock your screen for ransom or steel your ID. Of course I didn't do anything that he asked. I just asked him if some people actually fall for this s**t? I then told him to go f**k himself!!
