How to create Autorun.inf virus

This document explains you how you can form an autorun inf file. It further elaborates on the customization of the icon text and icon menu.
When we insert a CD, we find that the files on it can be run automatically. This is a utility provided to the users by Windows. However, before we can use it we need to verify if it is enabled on our system. Running a file automatically saves a lot of effort and time. This article gives us an insight into creating such a file and customizing the icon text and menu.

Allowing autorun

Windows provide users with simple utility that runs automatically applications found on a CD, when inserted in the CD drive.
To make use of this option, you must verify that it is enabled under your system configuration. If it is the case, upon inserting a CD or DVD,Windows will try to open an application.This procedure is due to the "Autorun.inf" (primary instruction file associated with the Autorun utility) found at the root directory of the CD.

Creating an Autorun.inf file

First create a new (text-only) file and name it as autorun.inf.; once created, open it with your favorite text editor (notepad) and type in the following syntax:

[autorun]

parameter=value

Basically it should be like this :

[autorun]

open=myapplication.exe

Variations

If the selected application is found in a sub folder, the path must be specified:

[autorun]

open=folderA\folderA1\myapplication.exe

If an argument is to be passed for the application to be auto played:

[autorun]

open=myapplication /argument

Customizing the icon

If you want to change the default icon add the following syntax:

icon=icon.ext

Example:

[autorun]

open=myapplication.exe

icon=myicon.jpg

The icon file should also reside in the root directory of the CD.

Customizing the icon text

Simply add the following command line:

label=My application

Customizing the icon menu

To edit the menu that appears when you right-click on the icon simply add the following syntax:

shell=start shell\start\command=path/myapplication.exe 

shell\start=Run Application

shell\read\command=notepad++.exe files/readme.txt 

shell\read=open readme.txt 

Keep in mind that the following parameters should be defined: shell\*\command and shell\* ,as they are the keywords, firstly for defining the application to be executed and secondly, for the text displayed in the menu.
