A few questions..

A few questions.

So, i'm fairly new to hacking but sorta not new at the same time, a few questions i need answered.

What's the difference between external and internal?

Can i use an injector with an exe?
Can i use an injector and enigma protector at the same time?

What's the most reconmended injector?

I'll be corrected if I'm wrong

External hacks are usually .exe files, more or less it's a click and run kind of deal.
Internal hacks are .dll files that require the user to inject their hacks.
Opinions are varied but both types of hacks have the same detection rates.

I do not believe injector's are necessary for .exe hacks, I also don't think injecting an .exe works.
You can use an injector and enigma/VMProtect, follow the hack creator's instructions when it comes to that. Mercy's PolyLoader is also a popular option around here, although it seems like 2.0 has less issues than his recent release.

I don't typically use injectors, but Extreme and PerX injectors are the commonly used ones around here, with Extreme being the one I've seen pop up the most.

Also to save everyone else the trouble, typically hacks/injectors/etc will set off your virus protection. All files posted here go through an approval process that is rather meticulous. In reality they are simply false positives, so please don't fret if this ever happens.
