Hello Jean-François,

My question is, can I use the 30 that is not detected, have them pass through VirusTotal and gradually upload them to the www.clamav.net/reports/malware page. 


You can use clamsubmit to submit a file. To submit 30 files to ClamAV you can create a bash script.
It is faster than using the webform on clamav website.
Syntax is :
clamsubmit -e your_email -N your_name -n the_file_to_submit


So would it help to make clamav better or is it going to be just very annoying and get myself banned....


As far as I know, it is OK to submit a lot of files to ClamAV team. I do it sometimes too.

I sure would like to have clamav detect at least 90% of the lot.  It would be a long process but my health is not good and I am stuck home with nothing to do.  Doing that would at least make me feel useful a little.


Yes, it will take time to ClamAV team to create signatures based on submitted samples.
If you want immediate better detection you can use 3rd party signatures for example :

https://sanesecurity.com/usage/signatures/

Maybe the best point is to submit samples to ClamAV that are not detected by anyone ?
Btw, be sure to submit *malwares* to ClamAV. Malware collections like VirusShare contains a lot of false positives...
