Batch File Prank

Hi Boffins of the world!

Today I'm going to show you how to right a random batch file prank.

I'll say it right now, this is NOT A VIRUS, it's a piece of harmless fun!

Have fun!

Step 1 Getting Started

 Okay, first you need to open notepad as this is where you'll type in your batch file.

 great file! the only thing i would add is: display the message warning in a message box with msg * WARNING VIRUS ATTACK! or you could make a continuos loop to the message, making it unclosable, with this code:

:msg
echo.
echo msg * WARNING VIRUS ATTACK!
goto msg

but besides that, thanks for the file!! 

[messmaker]

@echo off
:A
msg * VIRUS ATTACK!
ping localhost -n 1 >nul
goto :A





that one is readable and better, even though i just made it up then|:

[rahulbumwatt]

Nice

[nova]

Woops, yeah, i meant top put just msg, instead of echo msg

[jediking14]

The msg* thing never works with me...

[messmaker]

@echo off
msg * hello
msg hello2
pause





Run that and see if one of those commands work.,

[nova]

yeah, sometimes it decides to screw around with you, it's kind of annoying...

[jediking14]

Feel ya on that brother.

[nova]

Finally. someone who knows the feeling, i tell people this and they're like what?

[rahulbumwatt]

 Do you mean...


:A
@echo off
echo WARNING VIRUS ATTACK!
goto A

But that would open it so fast you wouldn't be able to read it!

BUT, i could do 

:A 
@echo off
echo WARNING VIRUS ATTACK!
pause
goto A

And that would work.

Thanks for the suggestion though!

[messmaker]

@echo off
msg * Windows has detected this as a virus. Please wait.
ping localhost -n 4 >nul
echo Windows is deleting the file...
ping localhost -n 3 >nul
:A
msg * VIRUS ATTACK!
goto :A




I just wrote the code then and i didnt test it, but it will work (:

[nova]

 no, if u put msg * a message box appears and stays there until you close it, with this code you can't close it, very useful! the msg box is seperate from the file. 

[rahulbumwatt]

 OR did you mean a .vbs file?

[nova]

 btw u would want to put that code at the end, because it will prevent the duration of the fileand you will need to shutdown thecomputer to get rid of the box, hope this helped!!

[nova]

also, would you like to collaborate on a large batch file?

[rahulbumwatt]

 Sure.

Right now i'm working on a real(ish) virus instructable.

If you'd give me your email or something i'll send it to you!

could i be in on this? (:

[nova]

Sure, we never really did figure out what we were going to do, so for sure.

[rahulbumwatt]

Right then! we may as well get started! Nova, you already have my email, messmaker, ive sent you a private message. reply soon!

[messmaker]

i have added you both to windows live.
im looking forward to working with you both.

[nova]

Absolutely, rahulbumwatt, you could start a group email maybe? As i don't have messmaker's.

[messmaker]

im really sorry to say, but that code fails :P


if i fixed it up a bit and sent you a code, could u edit it with a proper code?
