70 Chapter 5 Securing System Preferences
Turn off extensions in the Advanced pane of Classic preferences. Although Classic is not
allowed to interact directly with hardware, you might have several extensions that are
related to hardware and are therefore unnecessary.
You can also use the Memory/Versions pane of Classic preferences to view the
applications running in Mac OS 9. By choosing to show background applications,
you become more aware of any malicious applications running in Mac OS 9.
