Hello,
Seems strange, but we'll need to have a look to the logfile to confirm that it's indeed AdwCleaner the cause of your issue, but it's very unlikely.
I think it is due to the removal of a map "Windows/sources" but I am not a specialist.
Can you give me more details on that? When and where did you see "Windows/sources"?
Can you reboot with this liveCD: https://toolslib.net/downloads/...
