Scram, you scammer.

    Today I was on the computer when the phone rang.  The caller said he was from Windows Technical Department, and this was a check-up call.  He asked me to turn on my computer so he could do the checking for me, the customer.  I said no thanks, and hung up.  He called back, still wanting me to turn on my computer. I asked him his name and he said John, and he "likened to give proper knowledge." I told him I was sorry but I could not trust any incoming calls, and asked  for the  telephone number of his company so I could contact them. He supplied me with a number, but still wanted me to turn on my computer.  (He did not know it was already on.)  I hung up again.  Later I tried the number he gave me and the message said it was "a canceled number."  Big, bad John.
