While I would recommend everyone to disable this (unless you absolutely need 3rd party sales), it ultimately doesn’t solve the problem that the game has malicious scripts and potentially backdoors that enable exploiters to ruin any server.
There are several articles/topics on the DevForum that go over removing virus scripts and backdoors, here is just one of them. I would recommend you to search up some resources as well to ensure that your game is safe for players.
Glad to see that your issue has been resolved. However, that is only a bandaid solution. If it’s caused by a required ModuleScript, all the owner has to do is change out the code for something else that has the potential to inflict more trouble. This doesn’t require any input from you, anything they do would go live.
I would recommend working to remove the source of the problem now that you have the immediate issue fixed. I’ve written a guide on how one should tackle a situation like this here:
I’m not saying that you have to do this immediately, but it should be something on your radar to do before more issues arise. If you have any questions, let me know
