6.2. PrivacyScan tells me I have to close applications, but I don't see them in the Dock!

In order for PrivacyScan to work correctly, apps that are selected for cleaning cannot be running while PrivacyScan is performing a scan or cleaning privacy threats. PrivacyScan will alert you when you need to quit running apps. Click the magnifying glass icon in the Application Alert screen to switch to that application, and then quit the app from its application menu or by pressing Command-Q (⌘-Q). After quitting all running apps listed in the Application Alert screen, PrivacyScan will be able to continue the scan/cleaning of privacy threats.

Note that some applications might still be running in the background even if their icon doesn't appear in the Dock; be sure to use the magnifying glass icon to locate and quit those apps as necessary.
