How to create "Deadly" shutdown

What happens if your computer always shutdown or restart repeatly everytime you turn on your pc? ;-))
Maybe your pc has infected from some viruses OR has been tricked by some person :-D

AUTORUN

What is autorun? This is command on windows xp system that allow any command / programs run automaticly as the computer starts. In other words, there's nothing program that could'nt run automaticly if theres put in command into it. yeah NOTHING! except the commands is wrong or empty.
In this case, i'll use this autorun function to doing some tricky purpose. hehehe...:-D
The victims from this trick will found it the computer not stop to shutdown / restart whenever they turn on their pc...
To doing this trick, we'll create some shutdown or restart function in hardisk first.
Now, just right click mouse on desktop, then choose New > Shortcut > type this command: SHUTDOWN.exe -s -t 01 .This will create the SHUTDOWN function.
or
SHUTDOWN.exe -r -t 01 .This will create the RESTART function.
Then click next and finish. The name of shortcut you just created was shutdown.exe (you can rename it whatever you like, but i just leave it anyway it is). Then you store that file in C: or wherever you like.
-----
All you have to do now is put the command to execute that shutdown.exe file automaticly (autorun).
1. Go to Start > Run > type regedit

2. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

3. In right of windows, right click mouse > New > Key. This will add new key string there

4. Double click that string, then: (value name: type whatever) (value data: type "location of the file + file name"). If your file locate in C: then type "C:\shutdown.exe"
5. Done...restart ;-)

NB: to turn it back normal, go to safe mode then delete the shutdown.exe. restart
