Having an autoclicker on your computer won't necessarily lead to an automatic ban in Valorant as long as you're not using it in-game. However, Riot Games' anti-cheat system, Vanguard, is known for being very strict. Even if you don't actively use the autoclicker during Valorant sessions, the software might still be detected, and it could raise red flags.
To be safe, it's best to avoid running or having any software like autoclickers or scripts installed while playing Valorant to minimize the risk of accidental detection.
