The phantom virus
"Herobrine, the artificially intelligent virus, was deleted. The computer it resided in was completely destroyed. Without their leader, the few survivors of its evil army were cast away into the shadows. It looked as if there would finally be peace and happiness throughout the servers of Minecraft. But suddenly, and mysteriously, software began misbehaving... What seemed at first like harmless glitches quickly became dangerous. Pigs begin walking backwards, it starts to snow in the middle of the desert, and sheep are falling from the sky. Gameknight999, the User-that-is-not-a-user, has no choice but to investigate."--Amazon.com.
