Normaly they aren't detecting the injector itself, they trigger on the Injection's itself(ex. Hooked openprocess, loAdlibrary, wpm & rpm, CreateRemotethread exec.).
To be on the safe side, you shouldn't use any other injection method than manual mapping your module right after the process started.
And that's why my tip works out very well here , since there's a lot of different injectors in each section and different injection methods.
This is pretty much solved and there's no reply from OP.
