Introduction: How to Create a Virus and an Anti-Virus From Command Prompt {CMD}
Hi Guys,
This tutorial is to teach you how hackers create viruses, it would also teach you how antiviruses work and the simple way to create your own antivirus.
Disclaimer: This tutorial is for educational purposes only. Although this could be used to create a very troubling Virus, you should only use this for experimental reasons. This virus does not attack your computer's operating system environment and therefore should be safe. Please do not use this maliciously.
Launch the virus and see if your antivirus can pick on it. This would help you know if your antivirus is strong and suitable.
Step 1: Creating the Virus - BloatWare
Create your target folder - this is the folder you want your virus to attack.
For demonstration purposes, I have created a folder called Test under the C Drive.
C:\Test
This virus would create an endless number of text files which contains a different number in the text document each time.
@echo off
color 0a msg *You have just launched BloatWarez %random% :Reckon echo This is bloatware #%random% >C:\Test\%random%%random%.virus.txt goto Reckon
PS: The code above will bloat the folder as it would create an infinite number of text documents
Remember that you can change what the user sees in each document so "This is bloatware #%random%" could be anything of your choosing.

Step 2: Creating the Anti-Virus
So now we have identified the effect of the virus, let's now create the antivirus.
An antivirus, identifies and removes (quarantines) the infection. We start by writing the following code;
@echo off color 0a msg *Removing BloatWarez Virus del /s *virus.txt echo Virus Successfully Removed pause
Go ahead and test the virus - bloatware.cmd and once you have created the viruses, use the antibloatware.cmd to remove the files. Download AntiVirus file and use it to your pleasure.

This isn't what the project is for. It is for showing how antiviruses defend, making malware or viruses and sharing it is illegal most places.

I think this a very cool project! Most of the projects here just show how to make a prank or fake virus, but this project is legit, and that's awesome!

This doesn't explain virus applications work and/or are made in the slightest. Nor does it explain what an anti-virus actually does and what techniques it deploys in order to detect virus applications. Maybe research and explain some of the techniques such as heuristics and simple checksum comparisons to a known malware database.

Thanks, I would include known techniques used as heuristics and simple checksum comparisons.
