Backdoor Help

i downloaded tons of leak for my server and there is a backdoor that is popping postal dude whenever i press W A S D, i know how to detect backdoors well but this one has no suspicious elements that making it noticable also i have too many addons that making me unable to find the code :C

---

ok i just found out that this is not a backdoor and almost half of the gmod players experienced it, it is just BlackWatch [PM] addon being hacked :D
