Injector

I created an injector with visual basic .
I followed a tutorial from youtube .
So i wanna know if there is something i need to to in order to make it undetectable .
Or it is officially undetectable when newly created .

same thing with me. but every time i go to inject it, my csgo.exe stops working. wierd

code=signature
for exmaple
cheat()
hello
=
