Looking at that link I assume that what you are asking is malware that uses anti VM tricks. Am I right ? If yes, then redpill etc are what you are looking for, start at the following links and ask me if you have any problems.

May be I will release my paper on these concepts soon.

So basically you are asking for source codes of malware that uses Anti VM tricks. I don't know wheather it is allowed to discuss theses things on the forums. So wait until don allows us to share these things. Or read a bit about google hacking. There are thousands of repositaries of malware sources out there.

Until then I suggest you to write simple "hello world" viruses and then use Anti VM tricks in them (from the links that I gave you) to test wheather the tricks works on the desired platform or VM.
