I just received something like this an hour ago.  I was surfing Ebay and laughed when I saw PimpCash.  Having to see if it was real, I went to pimpcash.com. Immediately something like what you showed came up.  However, for me, it pretended to be my service provider and gave me a number to call.  I confess I did try to call but the ring didn't sound right.  Sounded like an old telephone.  I hung up and rebooted my computer.  Things seem to be ok now.  I ran a quick scan and all seems to be okay.  Is there anything else I should do to check to see if my computer is okay?
