I am trying to exclude a file from being incorrectly quarantined by Windows Security. It is a definite false positive, it is an application I have been using since Windows 7, and has recently been quarantined by Windows Security.
I go through the following route:
Windows Security > Virus & Threat protection > Virus & Threat protection settings > Add or remove exclusions
However, when I attempt to add the file in question I receive the message:
"Operation did not complete successfully because the file contains a virus or potentially unwanted software."
I have no other antivirus or antimalware software installed.
