Only files in the System Folder of the type "INIT", "CDEV", or "RDEV" are
searched for INITs at startup. In fact, with System 6.0.2 and later, only
visible files in the System Folder are searched for INITs.
The INIT 29 virus installs an INIT in every resource file that is opened,
in which a code resource is installed, excluding applications. Because the
Desktop file is a resource file and not an application, an INIT is
installed. This INIT is never activated.
