Hi,
First of all, you should disable the "JS" compression functionality from your Joomla, so you will see what JS files get loaded to your website by looking at the source codes.
Secondly you don't need to publish the "zoom effect module" in all Joomla pages if the zoom effect creates conflict in some other pages, you can limit the loading of this module only where it is needed (which is Virtuemart Product Details Page only)
Regards.
