How to make someone think they have malware: Batch File Instructions

This post will contain instructions on how to create a windows batch file that when run will likely make the victim of this prank think that they have malware on their computer. This post is intended for entertainment and amusement purposes only. It is illegal to send batch files electronically, so please do not place a batch file anywhere on the internet.

This post will be somewhat like a previous post in which I gave instructions on how to create a piece of "malware" using VBScript. All I am providing is instructions on how to make the batch file on your own computer, not the actual batch file.

Before we continue, did you read the warnings above? I mean it, read the warnings before continuing.

Got it? Good.

Step #1: Open a new notepad document. You may find notepad by Pressing the windows key and the R key at the same time.

Step #2: Copy and paste the following code into the notepad document:

@echo off
title VIRUS
color 0c

echo YOU HAVE A VIRUS ON YOUR COMPUTER
pause
echo CONTACTING ANTI-VIRUS....
pause
echo DO YOU WANT TO DELETE VIRUS?
pause
echo ACCESS DENIED
echo ACCESS DENIED
echo ACCESS DENIED
pause
echo ACTIVATING VIRUS.....
echo VIRUS ACTIVATED!!!!
pause
:1
dir/s
goto 1

Step #3: Save the document by clicking the file button at the top of the notepad window.

Then click the save as button.

Step #4: Save the document as anything you would like. Just be sure that at the end of the name, you place .bat at the end. (Example.bat) Also make sure that the new batch file is saved in a convenient location such as your desktop, or the desktop of your victim.

Step #5: Keep in mind that if you plan to use this to prank someone, it would be best to create the batch file on their computer. Lure the victim away from his or her computer for a few minutes, then preform steps 1 through 4.

Step #6: Call your victim to the "infected" computer and entice him or her to run the batch file.

Step #7: Some wise computer users will be suspicious, so you will have to convince them in some way to open the batch file.

Step #8: Have fun watching the reaction on your victim's face.

Thank You for reading. I invite readers to comment with any comments or questions. And for those of you wondering what the completed prank will look like:

Once run, the batch file will run through a non stop list of files stored on the desktop.
