Okay heres the thing,
Try to delete that depthudline and see if you're still banned.
Try to re-install garrysmod and see if you're still banned.
Try to join RND servers with a clean gmod.
Try to wipe your whole hard drive and start from scratch.
See if you're still banned.
The "virus" that you claim SHOULD BE gone..
AND if you are STILL banned, that proves to you that you have been banned not by the anti hack.
You have been banned by coolz (the server owner) for the reasons you provided in this thread.
If you're trying to find a way to be unbanned by making up excuses that fill up the fact that "you have been banned because of a virus in the depthudline" then it's not gonna work. If coolz banned you, there's no way getting around that.
He's the boss man.
I don't know how long you will be banned. Maybe talk to the boss man about that since he's the one who banned you.
[spoiler]Also, if you delete system32 in your computer, it should run faster making your gmod super epic[/spoiler]
