Hi,
i've got a BIG problem! I'm writing an exe packer, with some extra 
security features. One of these features is, that it should make the exe 
file, that it should pack later, immune to any debuggers. 

I thought i can do this by adding some self modifying code. That's no 
problem, but how can i link this code to an exe file. I think that's kind 
of the same technique that some viruses use to hide themselfes against 
anti virus scanners. I wan't to use this technique to hide the programm 
against debuggers and crackers. Is there any one out there, who can help 
me writing a link routine to add this code to a programm?
