Brainwashed

Hello,

I have a laptop windows 7 installed. Well I think it was yesterday it happened. My computer just randomly says "BRAINWASHED". I have no clue where it came from or why its saying this. I'v been going to my regular sites, no downloads. The only change thats happened is that I've been playing a game with friends online via skype. I ran malwarebytes just in case but nothing was returned infected. Im at a complete loss. I've seen a few with this problem recently, but no solution has been made.

Any help would be appreciated thank you in advance.
