This is a bit peculiar. If I try to import the right task into the Registry folder, either nothing happens, or I get the corrupt message. The window remains blank, however. If I try to delete the Registry folder, either nothing happens, or I get the message
"You must delete all tasks and subfolders from the folder before the folder can be deleted."
I've accessed the Advanced Explorer option in regedit and the Superhidden key has the correct value of 1.
So there seems to be a task in the Registry folder which I can't see or delete.
I've run another scan with Repair Tasks. Here are the results:
