Did you see my previous reply? I got my backup to run by changing the configuration not to backup the AppData folder. Do you think I still have malware? Malwarebytes doesn't find anything. It only seems to be an issue if I try to backup the AppData folder.

Thanks! I tried a couple methods to delete Shadow Copies. Nothing worked. Next I changed my configuration so I would no longer backup AppData. Now my backups run successfully. 😀 Maybe I still have malware 😬 but my backups run.

Here's the log file. mbst-grab-results.zip

After disabling Malwarebytes my backup still failed. That was surprising. My backups started failing the day I installed Malwarebytes. The error says "Operation did not complete successfully because the file contains a virus or potentially unwanted software." but i don't know what file the message is talking about.

After installing Malwarebytes my backups are failing almost all the time. I can't find a pattern when the run good. I have Windows 11 Home and I'm using Windows 7 Backup and Restore and Microsoft Defender. Backups fail with event ID 4104 - The backup was not successful. The error is: Operation did not complete successfully because the file contains a virus or potentially unwanted software. (0x800700E1). But I can't find any indication what file contains a virus. I just know it happens after installing Malwarebytes. I think there is some conflict between Malwarebytes and Windows Backup.
