Since Grand Theft Auto V launched on the PC, players and developers have been having fun editing the game with a series of amusing modifications.
But behind the humpback whales raining from the sky or the ability to fire entire cars instead of bullets something more sinister is going on.
According to a post on GTAForums, one user noticed that two popular modifications had secretly added a file called “fade.exe” to their machine.
The file had granted itself access to the internet and turned out to be a keylogger – a program designed to record and steal passwords.
“The Fade.exe had hijacked an official system file, the C# Compiler, and was accessing the internet while keeping what seems to be logs of my system in the hidden temp directory,” wrote the affected user, who goes by the name “aboutseven”.
“I noticed all the mods that I had downloaded for GTA V had matched the date when this folder was created.”
The two modifications in question were “Noclip”, which lets players look at the inside of objects in the game and “Angry Planes” which creates planes that start attacking you.
Any sites that host these two modifications have since removed them, but if you’ve downloaded one of them yourself then it’s important to check you haven’t been hit with the virus.
Thankfully, “aboutseven” who spotted the infection, has posted a detailed step-by-step guide to removing the nasty virus.
