While you've been busy enjoying guns that fire cars, piloting flying saucers or swimming 'round a flooded Los Santos thanks to mods for the PC version of GTA V something darker's lurked beneath the surface. GTAForums user aboutseven noticed that a C# compiler was running in the background on his or her computer and traced it back to a file dubbed "Fade.exe." Upon further inspection she or he spotted that it was using internet access. Turns out it was a keylogger. Process of elimination deduced that "Noclip," which allows you to examine the insides of objects freely, and "Angry Planes," which spawns incredibly, well, angry, planes that attack you with kamikaze-like fury, were the culprits behind the malware infection.
