Such virus may be responsible for stealing hard disc space, accessing private data, corrupting information etc. Creating a computer virus is easy, and in this post, I am going to take you through how to develop computer virus using C programming language. Please, use the programs presented here for study purpose only. To create computer virus using C, you need a good knowledge of C language, and a tricky mind to understand how the virus will infect your computer.
The virus programs presented in this post are all different, and each of them infect your computer differently as they have different functions. The source code which when executed creates a copy of itself in all the other files that are present in the same directory. These virus generally tend to form a network, and easily spread all over the computer.
I suggest you to understand and analyze these programs, but not run them in your computer. The source code of this virus is written and compiled in Turbo C. Before going through the source code of the virus, I would like to put forward the algorithm for this virus. It works following the major four steps given below. Testing this virus normally may infect your computer. So, in order to test this virus program, you are recommended to follow the following steps:.
This virus is so simple to create. The only thing you need to know is how to approach the setting menu of your computer. The source code is short. The first line is to reach the setting menu of your system and the second line to shut it down.
It is not so harmful to test this virus on your computer. If you want to make macro viruses, learn the macro language for your target programs such as Microsoft Office. Visual Basic can be used to create malicious programs for Windows users. Start writing your virus. This will be a long process, especially if this is your first time coding something. Experiment as much as possible, and research ways to replicate your code depending on the language you are using.
There are tutorials on forums and community blogs for a variety of languages. Research polymorphic code. This will alter the code of your virus every time it replicates, making it difficult to track with antivirus programs. Polymorphic code is fairly advanced, and is implemented differently in every language.
Research ways to hide your code. Besides polymorphic coding, there are other ways to hide your virus. Encryption is a very common tool used by virus developers. It takes a lot of practice and reading, but it can go a long way in increasing the lifespan of your virus. Test your virus. Once you have a prototype up and running, test it out on as many different machines and setups as possible. This will be easiest if you are able to set up virtual machines in different configurations. Make sure that you keep your tests contained so that you don't accidentally release your virus before you are ready.
Put the test machines on an isolated network and see the effects of the virus spreading. Adjust your virus's code as you observe it working on the test machines. Fix any issues that it runs into. Release your virus. If you're satisfied with your virus's performance, it's time to release it. Before you do, however, ask yourself if you're prepared to face any consequences that may come from releasing a virus into the wild.
It may be better to use that experience and work on new projects. Yes No. Not Helpful Helpful To prank a friend maybe. Or maybe you want to get revenge on an old enemy.

Not Helpful 64 Helpful Create a backdoor or an administrator access secured with a strong encryption that will recognize your protocols only. Not Helpful 55 Helpful Not Helpful 53 Helpful By learning some batch programming and performing some basic operations that "might" look like virus ones.

You can make a trigger like this: If the file StopVirusRunning. Keep the virus in the same directory as the file. Well, viruses are of different types as there are trojan horses and much more.
However, have you ever thought about creating a virus? You can create one within seconds, and it is possible with some simple methods that I will discuss in this post. Many of you will think the methods must be on coding, but nothing like that.
The tricks are based on Notepad. Just follow the below steps for creating a virus within a minute. Additionally, you can remove malware from your browser if it is infected. Now save this file as virus.
Now running the file will delete the C drive completely, and the operating system of the respective computer will get corrupted. Note: This method is only for knowledge purposes. Item i. Eject Next End If wscript. When you double-click on this file, you will be amazed at what this simple, harmless virus can do. To stop this virus, you need to open Task Manager, select the process tab, and end the wscript. If you have an active antivirus, your antivirus program will remove this file in no time.
This is a harmless virus, and it will not destroy your PC. You can use this notepad virus scripts to prank your friends. You need to type the following code in the Notepad. Save the file in a. Well, if you want to fix it. So, this is one of the best notepad virus pranks.
