There's a higher level than any interactive administrator account on a Windows system, called NT AUTHORITY\SYSTEM, and this is the level drivers and this sort of anticheat run at.

This is the level you would need to be to start doing really nasty things like keylogging, hiding processes/network/file activity, and generally making your computer gaslight you. This also means it can gaslight any antivirus you may be running.
