A Collection of Batch Computer Pranks

Due to the large amount of instructables I have seen here that detail ways to make batch file "Viruses", often times using the exact same code, I'm making this 'ible to show a comprehensive list of the ones that I know. Keep in mind, some of these can actually be dangerous if used, so be careful!

Some of these aren't exactly "pranks", and should only be looked at for educational purposes.

Disclaimer: I am not responsible if you wreck somebody's $2,000 water-cooled super awesome gaming computer, be it for a silly grudge, or accidental, using the code shown in this instructable.

Step 1Making a Batch File

So, in order to input the code described later, you're going to actually need a place to put it. For Batch, you can use the command prompt by going to start>run>cmd.exe, or making a ".bat" file in notepad. Make sure to save it as all files and with a ".bat" extension.

Hey man XD... i really appreciate all these codes XDD... But i have one certain problem. Right now i have this code:

@echo on

:Top

color 02

prompt Hi, You Have Been SCAMMED XD

start color 0c

pause

prompt Hi, You Have Been SCAMMED XD

prompt Hi, You Have Been SCAMMED XD

prompt Hi, You Have Been SCAMMED XD

prompt Hi, You Have Been SCAMMED XD

prompt Hi, You Have Been SCAMMED XD

prompt Hi, You Have Been SCAMMED XD

prompt Hi, You Have Been SCAMMED XD

%0

rem ---------------------------------

rem Self Destruct

del /f /q %0

rem ---------------------------------

goto top

%0

(the pause is so to not destroy my computer whilst modding it XD)

...

My idea for this, is to open command prompt (pretend to be deleting stuff...), then open up another 8 command prompts (make them look like the one before, scrolling and pretend to delete stuff) and repeat the process....

ANY SUGGESTIONS WOULD BE APPRECIATED XDD

Does it fix on restart?

I wouldn't recommend trying it.

I might use these as temp files for a exe so I can demonstrate the dangers of a virus in school. :P

I think the school will apreciate the demonstration. lol

I've tried using this, but every time i try, an error message comes up saying invalid character, line 1, character 1

I tried this virus with a fake Outlook Account, and Trend Micro said this was the HitOut virus. XP

Lol the mechanism action is basically the same between the two.

Shouldn't you associate some crazy file type with exe, then have it use the list to copy, rename, and place into a hidden directory, then edit the file by taking %0, removing .exe, then adding the type on the end, and then use that so the file runs afterwards?

I'm gonna use this. Put it all together (well, most of it) to make a mega virus with some other touches (once it's done it blocks input, turns up the volume and goes to http://www.youtube.com/watch?v=CyzyOnOh9A8) to send to danooct1!
