Host Machine: Apple II GS. Host Files: Boot block virus Increase in Size of Infected Files: n/a Nature of Damage: Erases boot blocks of disk in slot 5, drive 1. No files are damaged. The damage done by this virus is minimal --it destroys only the boot blocks of a 3.5" disk (5.25" disks and hard disks seem to be immune), leaving all the files and directories intact (it can, however, render some copy-protected games unusable). LOAD RUNNER has a finite life-span built in -- at the same time it starts damaging, it also stops propagating, and being a boot block virus, it destroys copies of itself when it destroys the boot blocks. Virus copies itself to $E1/BC00 thru $E1/BFFF. Virus resides in the boot blocks of a 3.5" disk. Copies itself to $E1/BC00 when disk is booted. Copies itself to disk in slot 5, drive 1 when CONTROL-APPLE-RESET is pressed. Propagation routine gains control by patching undocumented system vector in Memory Manager. Original boot blocks are not saved --virus contains code to emulate standard boot process. Infects disks in slot 5, drive 1 only. Infection of disks occurs when CONTROL-APPLE-RESET is pressed. Infection of host machine occurs when an infected disk is booted. Triggered by any date between Oct. 1 and Dec. 31 inclusive, of any year. Damage occurs when an infected disk is booted. If damage occurs, further infection will not occur. (Note that the damage process wipes the virus off of the infected disk.)
