Explanation / Answer

Before starting firstly we understand about .bat or batch file which is is a kind of script file in DOS, OS/2 and Microsoft Windows. It consists of a series of commands to be executed by the command-line interpreter, stored in a plain text file.

Step 1:

We install virtual box and install windows on it (https://www.virtualbox.org/). This step is very important as by running .bat file directly into computer that we created will freez your computer.

Step 2:

Open notepad and paste the above commands.

@echo off
echo WARNING virus has been detected
echo System Check
echo Virus quarantined
echo Click any key to delete virus
pause
:bm
explorer
goto bm

Explaination:-

@echo off, results in command prompts being hidden. use on to display.

echo is used to display.

pause is used to hold the program and wait for user response.

:bm here is a function

explorer is your browser opening request

GOTO bm is calling that function again and again mean it gets stuck in an infinite loop therefore computer freezes.

Step 6:

It's is simple yet very important step make sure to save file with .bat at the end instad of .txt.

Step 9:

shutdown -s -t 30 -c is cpmmand simply telling computer of poweroff after 30 seconds.

Step 14:

del "*.txt" this command is using wildcard which is very useful way to find , delete and do all sorts of things in bulk. * before .txt implies that any file ending with .txt is to be delete as in this case. It can be used at the end aswell.

Step 18:

Here the same code is used but this time files located at parent directory is deleted.

If you are still confused with any step ask me again. And the title of project is misleading these are not viruses , these are just basic bash scripting commands. One more interesting command for you. Enter this in cmd %0|%0 and watch the magic. Make sure it's virtual machine.
