You're probably right. The oldest versions of the System do not scan the System folder for INIT (Startup), RDEV (Chooser), and cdev (Control Panel) files; INIT resources contained in these files will not be executed. GateKeeper and Vaccine are both cdev files. You _might_ be able to install a hacked-up copy of Vaccine into the System file on your startup disk(s). You'd need to configure Vaccine on a more-modern machine... probably "protection on, expert display, don't compile MPW INITs, don't show icon at startup". Then, use ResEdit to copy the INIT and FKDT resources from the configured copy of Vaccine, and paste them into the System file on your startup floppy. You could also try configuring the copy of Vaccine to display its icon at startup time; you'd then need to copy the ICN# resource from the Vaccine file and add it to the System. I haven't tried this and can't assure you that it would work... but it's probably worth a try. Do it on _copies_ of Vaccine and of your startup floppy, of course! Best of luck! Dave, Thanks for the above. I tried it and although all the copying and pasting via ResEdit worked OK, no joy when I booted up with the new system. The Vaccine icon didn't appear and re-infection occurred when I used an infected disk on the machine. I have an application called "Immunity" which is supposed to protect the System file from re-infection by inserting nVir=10 code into the resource fork of the sytem file. It doesn't seem to insert it into other files that could be infected eg. Finder, MacWrite, MacPaint etc. Could I use ResEdit to copy the nVir=10 code and paste it into the other files/ applications?
