The following uuencoded program is a virus killer. It allows examination of a disk's boot sector, the removal of an auto executing boot sector and the installation of an "anti virus" on a disks boot sector. This anti virus is simply a program, on the boot sector, that tells the user (on boot up) that his/her disk is virus free. You may have a colour warning. i.e. screen turns red momentarily, (before desktop appears) on a colour system or screen becomes reverse (when desktop appears) on a mono-chrome system, a text message may also be printed to the screen saying "Virus free disk" and you may have a bell sound when you boot up. You may have any combination of the above three warnings. You may also save which combination that you like best. Thus if you have an anti virus installed on your disk and when you boot up you don't get your warning, reboot with this virus killer and check your disk. If you don't get the message "This disk has an anti virus installed" then something has written over your boot sector. Virus? Do with it what you will!
