VAC

Sorry, I'm not sure if this is the place to post it, but here goes.
I have two questions, one, does changing the name of a CSS Hack really make it VAC Proof? For example, hack.exe changed to mpgh.exe, would that change anything?
And the other one, are External Hacks VAC Proof? Thanks!

Rename the file do nothing about the detection

No.. It dosnt change anything its just the name.. The chaet is injecting source anyways if ure chaging the name x]
