I received a call from this number on my cell. Didn't answer so I was left a message that "stated my physical address was under Federal investigation and to return the call immediately." Caller had a Indian accent.
Didn't answer the phone, but apparently these people have a way to "double call", which doubles the number of times the phone rings before the answering machine picks up. Of course, they left no message.
Received a call from David saying that my computer downloaded malicious files 9pm-2am last night. Neither of my computers were on at that time. He gave me an Windows ID Number with a lot of alpha-numeric digits. He wants to call me back tonight when I get home from work. I suspected this was phishing and after reading the other comments, I will not answer his call.
