Moving a file

Hi,
I am trying to move a few files to another drive.
I get an error message that say they are infected with a PUP (error 225).
I can't find out what is going on.
I'd attach a screen shot, don't seam to be able to!!
Please can anyone help

Your problem is Windows related (Defender; unwanted files/virus), not DirOpus! Just google mentioned error message.
