Can't find quarantined files virus chest osx version

I can’t find useful help for my question, maybe this is due to my mac version of avast. I ran a a full system scan and avast found infections in my metasploit directory. I wanted to make AV ignore these files, but I couldn’t figure out how to do this. I ended up sending a few files to “Chest”, but when I went to Virus Chest I couldn’t find my quarantined files. How do I remove the files from quarantine, and how do I remove the metasploit files from the full system scan infection report? What terms should I be searching for to find my answers? Thank you.
