Help How do I turn zombies to none?

[xMatthewv]

Hey guys Matthew here, I was wondering how I turn zombies to none and make them all dissapear off the map. I know this kind of makes me look like a noob and that the whole game revolves around zombies but my friend and I just want to make a really good base without being attacked 1000 times like we have been. I have already set the zombies to none in the Project Zomboid Server settings but there was still zombies in my game, does the "None" option mean they all despawn or does it mean they wont spawn back.

Please can someone tell me!

Thanks -Matthew
