 General Comments: 
       The Boot Killer virus was received in August, 1992.  Its origin or 
       point of isolation is unknown.  Boot Killer is a non-resident 
       infector of the hard disk master boot sector (partition table) and 
       diskette boot sectors. 
       When the system is attempted to be booted from a Boot Killer infected 
       diskette, the Boot Killer virus will be read into memory, and then 
       the system boot will fail, displaying the message: 
               "Non-System disk or disk error 
                Replace and press any key when ready" 
       After the user has replaced the boot diskette, and struck a key, 
       the boot will the proceed.  If the boot diskette was a non-write 
       protected diskette, the Boot Killer virus will have infected 
       it, overwriting the original boot sector.  At this same time, the 
       virus will have infected the system hard disk's master boot sector, 
       overwriting it as well. 
       Systems infected with Boot Killer will experience frequent boot 
       failures from diskettes, as well as the system hard disk having 
       become inaccessible due to Boot Killer overwriting the master boot 
       sector.  Attempts to boot from the system hard disk will result 
       in the same message displayed above. 
       The damage to the hard disk master boot sector can be repaired using 
       various disk diagnostic programs, including Norton Disk Doctor. 
       On system diskettes, the DOS SYS command can be used to replace 
       the infected boot sector.
