Presumably, I'd like to have a custom scan which checks the /Applications folder and the system folders such as /usr, /sbin, /bin, ... how do I specify the later ones in the Custom Scans?
In the Finder, press command-g and type in the path. When the window opens, drag the parent folder to the add window in SAV, and it should add the path. You may have to click + first and drag it to the open dialog.
