Google indexes media with comments option

Hi

I stumpeled upon the fact that Google sometimes indexes product images (attachments) which apparently have comments available as an option even though I am using the newest woocommerce plugin and storefront theme.

Example of a product:
https://www.flickzone.dk/produkt/alien-3-dvd-special-edition/

Example of a page that Google also indexes:
https://www.flickzone.dk/produkt/alien-3-dvd-special-edition/alien-3-dvd/

Another example:
https://www.flickzone.dk/?attachment_id=387

How can Google discover this page and can I remove the comment option on this page?

I hope that someone has experienced the same issue and found a fix ??

Good night.
