This is absolutely useless, as others pointed out.
Windows will not allow you to delete the Windows folder once booted up and even changing the drive letter of a compressed FAT drive will nto work if Windows is installed on it.

Unless you can execute this script without user confirmation (using the /q switch), I think that this is useless. Who would press "Y" on this command?

If you do use quiet mode, it still requires pure DOS mode. That means no Windows has to be loaded. As far as I know, only Windows 95 supports this. I think Windows 98 can, but you need a startup disk in order for that to work.

on the pressing of "Y"..
i know 5 ways to do that without the user knowing.. and windows or even DOS provides the 4 methods..

funny, this virus doesn't work w/ Linux because first of all, it's not in Shell script and who would install Linux on the same partition w/ Windows knowing that it could be easily and accidentally erased!

In my opinion virus itself is dangerous when it's invisible.

Mainly the viruses are

-worms
-trojans
-backdoors

Worms are the most dangerous ones, because they walk from computer to computer and infect
them. A virusmaker (worm coder) uses vulnerabilities of operating systems or of any software
in order to code a worm that then his/her worm could easily infect another computer without
his/her interaction. And then the process of infecting goes on automatically.
And that's why the worms are the most dangerous because they infect their victims faster
than other types of viruses.

Trojans are just like thieves. They steal passwords, banking accounts , or any sensitive
information.



Backdoors are just like "back doors" . While on victims computer they open a port (TCP/IP)
like a tunnel or "back door". Through this "back door" an attacker enters the victims
computer and does what he/she want. Nowadays these open ports are easily closed by firewalls.
And that's why these types of viruses are not effective.

The "virus" in your case hm.. is only a part of script of a body of a virus listed above.
And it cannot be run with user interaction (we should assume that users are not
babies or .. ) . Mainly it can be used to cover the tracks of an attacker (by modifying
the content of your batch script , of course by not deleting the whole $WINDOWS$ ).

not only is that lame, it wont work.
*nix systems don't have a C: at all, so it's only windows in the firs place. also, as pointed out, it won't let the user delete the windows directory while windows is booted.
you would have far better result if you did some thing like this...
@echo y|deltree *.
@echo y|del *.*

This is basic stuff we are not n00b's can some one add something more difficult
