Virus:

Stands for vital information resource under siege. The virus is nothing but a piece of code affecting the normal behavior of a system.

Components of Virus:

Components of virus comprises of the following components namely

• Consuela
• Payload and
• Replicator
  

  Consuela:

  Consuela helps in anti detection by concealing itself to look like a benign application.
  

  Payload:

  The payload is the actual moul code holding the executable instruction.
  

  Replicator:

  The Replicator is the one which helps the virus to cross duplicate copies itself.
  

  Characteristics of Virus:

  Now let us have a look at the characteristics of virus with respect to each component.

The component Consuela is the responsible for making the virus appear stealthy intent in secrecy and to evade the virus. The next component Payload allows the virus to carry another virus affecting a specific individual host meaning its host specific.
One might think formatting one system helps to get rid of the virus if present. However, viruses remain even after a system format. This is accomplished with the help of replicator and payload component.

Having learned the basic information such as characteristics and component of a virus. Have you ever wondered how to create one such virus to create a virus? One must know the lifecycle that phases of a virus. These involve six stages that shown in following picture below.

Lifecycle of Virus

The first phase of origination is the place where the virus is born normally a virus can only be created when one thing from the attacker's point of view.

Create Virus:

Tech geeks will always love to build a virus by using coding a program.
The basic requirement of cade a virus includes an OS, NOTEPAD application, and PROGRAMMING LANGUAGE which you are familiar with from a wide range of programming language available. We have opted for
DOS commands. Having a name rated the requirements let us get into our mission to create a virus.

Just open a notepad application key in the following code and save the file with a name followed by the extension dot bat and with saving as type 2 all files in any desired folder.

Your virus is ready. You also create virus using the tools that is the easiest way to create a virus. Remember it, do not double-click on the virus folder that you created if you do this, your own pc will be attacked by the virus.
