Stuck in a move to Quarantine loop

A scan has detected a malicious file and is asking me if I want to move it to Quarantine. I'm selecting move to Quarantine and a new window appears saying threat secured but instantly a new window opens saying threat blocked with exactly the same message as the one I've just dealt with.

The threat name is Win64:UnwantedSig [PUP]

Any ideas how we can get out of this loop and get rid of the malware?
