If XP then if you searched for AOL and found these entries just right click and delete. Make sure that 'AOL' is NOT a part of a document folder or email in case you need to keep them.
Delete from bottom of list up. Ignore the 'access denied' and continue up the list and delete.
Reboot and start again. Should be that most of these folders have gone.
Remember to check each file in case the 'AOL' is part of a document so ignore those.
