Sounds like your are experiencing the same thing I have, Piracy by maleware.
Though most say Linux is immune. I have always suspected the MIB. Are you
polictically active in people vs. Oiligarch Bankster causes? Could be why. They
don't like people like us getting on the Internet, seems free speech mucks up
their New World Order plans.

I'm really keen to see how to fix this myself.
