Global access for Everyone Group

I have been tasked with taking over a Crystal XI Enterprise installation that uses the Everyone group to grant view access to all objects/folders. Where do I turn this off globally? In other words, I want the Everyone group to have no access rights to anything - so I can use created groups to administer access rights for obejcts/folders. Thanks for any help in advance.I have found the correct place for this under Settings. Thanks for your patience.
