They not terminate PatchGuard during boot, but instead of this they abuse its behaviour for protecting its own hooks! Which is quite briliant, because no-one is more suitable to protect your piece of code than windows protection mechanism Р Р†Р вЂљРІР‚Сљ PatchGuard itself very well written piece of metamorphic file infector Р Р†Р вЂљРІР‚Сљ in new era also bootkit functionality). Inspiration of idea, what to do with PatchGuard, come from writers of malware known as Goblin / Xpaj (btw.
