You need to Empty the quarantine area to fully remove the items.
Open AdwCleaner and hit the Uninstall button. This will remove the program And all items in quarantine.
I have found that a "fresh copy" should be used every 2 or 3 runs, maximum.
AdwCleaner[S0].txt should not be allowed above [S3] or it is full of Adware.
At the moment you are only saving quarantined items so they can be reinstalled if required.
Note the final lines in my reply on How to use AdwCleaner .
• Items that are deleted are moved to the Quarantine Folder: C:\AdwCleaner\Quarantine
• To restore an item that has been deleted (if necessary):
• Go to Tools > Quarantine Manager > check what you want restored > now click on Restore.
• To remove all items Re-open AdwCleaner and hit Uninstall to remove quarantined Adware.
