Man with heavy Indian accent called saying they were from the help-desk and they detected a virus on my computer. I played along. He instructed me to enter an IP address and then an access code into my computer, which I of course didn't do but convinced him I did. When he couldn't access my computer remotely, he got angry, called me a liar and hung up. They obviously are looking for idiots to give over access to their computers, at which point who knows what bad things they had planned.
