Don't know if anyone has been informed about this or not, but there is a lua virus going on around gmod at the moment, it will change your name and spam your friends saying stuff like "8cough* *cough*" meaning it could of spread (idontknow)
This has apparently reached a pretty good amount of servers.
And if you want to make sure you do not have it, go to your garrysmod/garrysmod folder and look for these files
If you have ANY of those, delete it instantly. Wouldn't advise going onto gmod much. Facepunch has been spammed with people trying to find a fix to this.
