Quarantine Question

This is a two part query -

 

First, why does Norton Security Suite only quarantine certain "high-risk" files while outright deleting others deemed only "meduim risk"?

 

Second, is there a way to prevent this without disabling most of Norton's functionality? It would be nice to have the option to quarantine a file rather than have it deleted. I've checked all the various settings and haven't found an option other than simply turning off certain tools, but maybe I missed something.

 

(I ask only because I often work with files that have very few users, and Norton has a habit of deleting them due to low File Insight reputation scores).

 

Thanks in advance!
