Module JS always loaded in admin

[Inxentas]

I have a strange occurence which I have a hard time explaining/debugging.

I have a module that contains a .JS file. I load this JS file using a hook, that is called when the template != admin... meaning it will only be called on the frontend. This works on my LIVE environment, but my DEV environment seems to decide to load the file somewhere. Since it contains a script that prevents scrolling, I cannot scroll in the admin.

Is there a circumstance in which modules load JS files placed in their folder? Perhaps when it has the same name of the module under certain PHP versions?
