Aplication locking on a Macintosh prevents a file from accidentally being destroyed (trashed) and to some extent from being altered. A user wants to know if locking Disinfectant on a hard disk will prevent it from being itself infected from a virus emanating from an infected floppy. The issue is whether we can trust a resident locked copy of Disinfectant to remain clean even if the hard disk on which it resides becomes infected. I have advocated that since we have no automatic virus checking software which is activated upon disk insertion or start up and since anyone can use the machine, the only way to be absolutely certain that integrity has not been compromised each morning is to boot up first with a trusted disk and run the trusted disk copy of Disinfectant against the hard disk files.
