The Easy Anti Cheat developers need to fix their junk software. It's not ASUS's fault in this case as far as I'm concerned.
According to EAC developers Aura Sync makes various hooks to "some DLLs" (I guess those might be directx dlls) for their "In Game Effects" which can be used by hackers. So no, it's not false positive, and not EAC fault either. This one is 100% on Asus and they should just extract all these hooks to separate service which can be just toggled off so it doesn't run and trip anti-cheats. But since most users are unaware of the fact that aura sync works in the same manner hacks do, they can go ahead and push blame on EAC.
