Avast won't quarantine malware in an ISO image

Avast Free Antivirus / Premium Security

Hello folks.

Couldn’t find a place to report a bug, so I’m guessing it goes here. I have an ISO image with an infected file in it, and Avast Free doesn’t seem to want to do anything with it. It detects the malware but won’t quarantine it.

Here’s the ISO image in question. (I didn’t see any rules whatsoever, let alone about malware samples, so I’m sorry if this violates something somewhere)

It detects the malware but won't quarantine it.
probably because it cant`t remove the malware from the iso so you need to delete or quarantine the entire ISO file
