It apparently is also on the other source engine games like L4D2 and TF2 but I haven't heard much about it from them.I just found out, when you're looking at the GMod server list and a server has !!! Behind the name of the server that means that server is infected and do NOT join it.
There's a virus going around on most GMod servers, it puts a .dll file in your source engine and you'll get vac banned. If you do play gmod do NOT get on any servers! Somehow it sends steam msgs to all your friends too saying *cough* and spams them http://steamcommunity.com/groups/TheIdl ... 9235593155 . Ill say it again do NOT get on GMod. It's being spread everywhere, the *cough* is actually kind of clever, if you get the "cough" you've been infected. It will send all your friends a msg saying cough, and if you join any servers after you got the cough you are spreading the virus so if you do have it get off, and if you dont have it yet be lucky and get off anyway. It hasn't hit all servers yet most DarkRP and TTT servers have it though.
This is not a joke.
One last thing if a friend sends you a msg saying *cough* I'm not sure that can spread it but I would delete them for the time being just incase.
If you have it already go to this link http://facepunch.com/showthread.php?t=1 ... st44583860 copy and past this into a text document then save it as a .bat then drop it into steam/steamapps/yourname/common/garrysmod/garrysmod
