We noticed that Norton has its own cache setting, which we've turned off in the hope that this rectifies the situation. As of right now, the locations whose Norton settings we've changed have not had further problems.

I tried running Procmon on a workstation while changing the cache setting, but am having a hell of a time figuring out where the setting actually gets stored. While we could certainly tell everyone who has it installed to change the setting, it might be nice to try to watch for it programmatically.

Thanks for letting us know about this.

It might be purposely difficult or impossible to find out how to change the AV settings programmatically. If it were easy, malware would (try to) do it.
