RECOMMENDED PROCEDURES FOR:

Preventing the virus from re-contaminating your hard drive.

If your hard drive has already been contaminated once and after you 
have removed the Stoned-B virus using the above procedure, you may 
use HARD.COM to prevent re-contamination from a floppy disk.

** DO NOT USE HARD.COM UNLESS A GOOD COPY OF THE BOOT RECORD EXISTS
   IN SECTOR 7 OF THE BOOT TRACK ***

NOTE: A good copy of the hard disk boot record will be in sector 7 of the 
      boot track if the disk has previously been contaminated with
      the Stoned-B virus or if you have used a utility program to copy 
      the good boot record from sector 0 to sector 7.

The program, 2.BAT, mentioned above, will display the contents of sector 0
and sector 7 of the boot track. If they both are the same and neither
contains the message, "This PC is stoned!",  then you are likely 
safe to use HARD.COM. To be absolutely safe, you must use debug or 
some utility software to copy the good boot record to sector 7 of the
boot track on your hard drive.
