Apple implements internally an encryption mechanism to protect some of their own executable like "Dock.app" or "Finder.app". This encryption can be applied to malware as well. If one does, anti-malware solutions can no longer detect the malware because of the encryption, but OS X has no problem loading such malware.
This same protection mechanism can be used on existing malwares that are already detected by Anti-malware products, to make them completely undetectable. Those same anti-malware products can no longer detect the malware because they don't understand it's encrypted.
