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...
