Cannot move threats to chest or delete?

That’s what I’m seeing. That’s the error I get.

Then when I try to delete the files, I get a “the system cannot find the file specified (2)”

Ideas?

I think the first one could be a problem that needs further investigation.

The second and third ones, ‘may’ be related to windows defender definitions updates (that may on update be removed, hence the file not found), this however is an educated guess not a certainty.

This needs further analysis by a malware removal specialist:
