Anyone who purchased or tried NextGen knew that after installation the initial batch of DLLs prompted you to log into your computer to modify certain settings. I was able to confirm that afterwards they would send you DLLs that overwrote certain files, as well as additional files placed in the /x86 directories—possibly including an x86 code section designed to prevent bypassing, especially since the locations where similar files were placed remained unknown. When Abblesys was cracked by John, several people provided information about this. The same goes for taskools—they contain x86 code sections (i.e., written in C++) intended to hinder deobfuscation.
