Every time backup runs it's triggers anti-virus in VolumeShadowCopy and I'm unable to get rid of it

As per the title I get this thrown up in MS defender every time a back starts:

Detected: HackTool:Win32/ProductKey
file: Device\HarddiskVolumeShadowCopy7\AppsPortable\Opera\profile\data\Default\Cache\Cache_Data\f_00020a

  • It’s a Windows 11 PC.
  • I downloaded Nirsoft’s Product Key utility which shows as a false positive.
  • I had it in a folder which is excluded from Urbackup.
  • However it appears that it was also cached when downloading in Opera Browser.
  • The cache has been cleared and cache file “f_00020a” shown in the message above no longer exists, and hasn’t for a month now.

It appears that every time Urbackup makes a shadow copy, the problem occurs. I have been unable to stop this:

  • I’ve listed all volume shadow copies in powershell and the one listed doesn’t exist.
  • I’ve removed all shadow copies from the volume.
  • The Shadowcopy number (7 in the example above) changes each time the backup is running and anti-virus reports it.
  • Where is this “f_00020a” file living? It’s not on the drive anymore and I’ve cleared all shadow copies. However Urbackup clearly makes it’s own copy temporally but I don’t know why it’s showing a filing that doesn’t exist.

Can’t you just tell Defender to trust that item and stop nagging?

Or turn off Defender for the next backup and see if you can get it to complete and move on?

I assume as the shadow copy is changing on every backup run it will eventually just purge itself…
