               THE SAFE WAY TO EXPERIMENT WITH VIRUSES


  The problem with fooling around with viruses is that you never know
  what damage there going to do to your hard disk.  I have a couple of
  so called viruses that when run, automatically screw up the FAT on
  all the disks in the system.  Well, theres a way around getting the
  shaft from these programs, and also to experiment with legitament
  viruses.

  The key is the DOS utitlity SUBST, make this batch file, and copy it
  to a floppy.

------------------------------------------------------------------------------
@echo off
subst d: a:\
subst c: a:\
------------------------------------------------------------------------------

   What this will do is send any access to disks C: and D: (the two
   hard disks in my case) to drive A:  So the only damage inflicted
   will be to the floppy in A:

   No programs can access you hard disk when this command is issued.  I
   use it all the time and as of now it has proved 100% safe.

   Oh yeah, if you dont feel like distroying a floppy every time you
   mess with a virus, you can do this teqnique from a RAM disk.

   Have fun...
