'Qual' volume mysteriously appearing as mounted volume on desktop

Using OCLP on old kit may mean we are aware of the risks and extended attack vectors that come with the territory - Has anyone heard of Mac ransomware that starts with a mysterious volume being mounted on the desktop named 'Qual' ? - no amount of info can be found about this volume, it's like it doesn't exist - and simultaneously Malwarebytes won't open ... as a precaution I shut it down and removed all but the essential system OS drive (PCI) - this is an old Mac Pro 5,1.

There is plenty on the internet about this being ransomware but as yet there are no other signs (eg '.encrypted' file types/renames and no viruses found by INtego Virus barrier etc - just Malwarebytes being weird

thanks in advance !
