This program enables the user to inhibit write operations, thus helping to prevent viruses from infecting the system.
The program offers three levels of protection: None, Partial and Total. With no protection, all operations are permitted. Partial protection prevents *Wipe operations and low level calls to FileCore_DiscOp, while Total protection prevents all write operations except *Compact. Any attempt to perform a prohibited operation will result in a 'Protected disc' error being generated.
When the program is run, the WatchRM module is loaded, and the application adds its icon to the icon bar. Protection is intially set to Partial. Clicking Menu over the icon pops up a menu allowing the protection level to be set, or any ADFS drive to be 'cleaned', as well as providing the usual Info and Quit options.
Changes to the protection level are reflected in the icon bar icon, which will be one of three text/sprite combinations:
Protection Sprite Text
Off grey Watch Off
Partial amber Watch On
Total red Watch XOn
Additionally drives can be cleaned. This involves compacting the disc, and then wiping the free space, which can otherwise be used as a hiding place for virus code.
