Aimware for Garry's Mod

Hi, I'm thinking about buying the Garry's mod Aimware subscription but I have a couple of questions;

Does it still get updates?
Does it have anti-screengrab?
If so, how good is the anti-screengrab compared to other cheats?

1. No, but its getting ported to V5 eventually. V5 is gonna have a bunch of bug fixes and probably bunch of new stuff added.
2. Yes.
3. Its the same in every cheat? It just disables chams.
