HOW TO CREATE A SIMPLE VIRUS ON WINDOWS XP

First of all i want to tell you that its not a virus but a windows xp bug.
The virus which i will create will shut down your PC if you click on it .I will also explain you how it works.
Steps for creating the virus:

1.) Right click your mouse ,go in new->shortcut, a message box will be displayed,

2.)Type this in the location : shutdown -s -t 120 -c "VIRUS MADE BY PRANAV" .Take care of spaces in between words

3.) Give any name for shortcut like My Computer or Internet Explorer

4.) Right click on the icon created,go in properties change the icon to my computer or internet explorer symbol

5.) Now click on the icon,a message box will be displayed indicating the time in which your pc will shut down

NOTE: This will not work on user account,i mean it will work only on administrator account.Also antivirus s/w cannot detect it.

6.) To stop turning of the pc,go to start -> run ,type shutdown -a ,the message box will get deleted

7.) Put the icon you just created in the windows startup folder in documents and settings.Now your pc will shutdown as soon as it starts.ENJOY THE VIRUS.

Now regarding the funda(concept) behind it.This concept is what i thought,it may be correct or wrong,dont know ,so if you think its wrong,you can post me abt it.

Actually whenever you press Turn off your computer from the Start menu ,there is shutdown.exe file(in your system 32 folder in windows) which will invoke the shutdown API which actuallys turns off your computer.

Now in this virus application we are doing the same thing,
shutdown -s -t 120 -c "VIRUS MADE BY PRANAV"
shutdown ---->shutdown.exe
-t --->timer(in sec) u can set it to any time 60 sec,30 sec,after this time ur pc will turn off automatically
-c ---->Any text ,u can modify which will be displayed in text box
I hope u must have understood,its not an virus ,its a windows xp bug
Oh i forgot to tell u the most imp thing ,shutdown -a stands for (a for abort) to stop the application
Any comments regarding this are highly appreciated
