Playing Warcraft 3: The Frozen Throne "arcade" mode, map Civilization Wars.
I don't normally play the old WC3 game but I decided to check it out again. After playing a custom map of Civ Wars, I started to watch a movie and then my internet connection became spotty. I restarted my computer thinking it just needed a reset. After it booted back up everything seemed fine, until I opened Warcraft 3 again. When the game launched (in full screen mode), the colors were off and it looked like the video display was trying to do some sort of 3D display. There were double "displays", 1 slightly blue/purple and one slightly red, so it looked like double vision with stereoscopic attributes. The game also had a text box in the bottom right corner that said Warcraft 3: Good, and some other text.
I exited the game and started to search Google for answers. Then I noticed the same display effect happens when I enter fullscreen on anything. I ran AdwCleaner and Malware bytes and came up with nothing.
I can't find any information on this virus or what it is called.
