There are various anti-cheat systems out there. The most known ones are:
- Riot Vanguard (NOT NECESSARY IF YOUR HACK IS FOR VALORANT)
The problem is that even though most are designed for a specific game, for example Vanguard for Valorant, it can be blocking for other hacks even for games that are totally different!
Which is why when buying a cheat please make sure to have all of these uninstalled:
- Riot Vanguard
Of course this does not apply if the specific anti-cheat is designed for that particular game
