Has your server been "Hacked" or "Backdoored"?

Then have I got news for you!

I've got two solutions;

One - Would require you to download all your addon/data/lua files and get a free 24hCrident server, then you'd upload the downloaded files to the Crident FTP and use the "Backdoor scanner" service.

Two - I would recommend getting the "CPE" addon for gmod, (I would recommend doing both as CPE doesn't get everything.)
