not sure if there is a definition for this, and I even prefer a metamorphic solution, but let me provide more details about what i'm looking for: 1. Static and Runtime FUD and must bypass all proactives. 2. Must have long FUD time including nod32. 3. Hidden start-up. 4. Custom icon/assembly 5. Other shit like: melt file, protect process, persistance, fake error message, etc 6. Exclusivity + Source code I will make the required adaptations on my source code so that in runtime the code should be encrypted / decrypted. Hope this put more light on my requirements.
