I used to work on an anti-cheat briefly, and migrated away form relying on Windows API to do this as the parent comment suggested, instead we used cache timing "attacks".

Antivirus was a concern but easily solved by the fact that cheats access memory many times a second, antivirus does it rarely if ever.
