Hello,

Please try to delete the files seperately after a scan.
This error message appears if too many bad files are found and should be deleted in one run.

If this does not help please delete the recovery function in Spybot - Search & Destroy.

Select "Settings" --> "Settings" from the toolbar on the left.
In the section "Main settings" please untick the checkbox in front of all three items "Create backups......".
That should solve the problem.

Or run a scan in safe mode:

That should fix it.
