How to make a virus in pc
Computer viruses are now more prevalent than ever and are a computers main security risk. The increase in Computer infections and other malware produced in recent years is one reason network security has become more popular. It is easy to forget that computer virus is nothing more than a line of computer code while researching the most recent information. Its core functions are the same as those of an internet browser, a portable app, or a virtual stage for entertainment. It is essentially a piece of computer code that was created to carry out a specific set of actions.
This means to infect a computer; You should be able to write code. Given the potential harm it may cause, it is debatable to assist people in creating computer viruses. However, there are legitimate justifications for learning how to create a computer virus. You might work for a company that creates malware as part of an entrance exam to mimic cyberattacks, or you might be employed by the government agency planning infections that will be used in cyberwarfare. Even though many network security experts won't teach people how to do this, getting a job in these positions without any knowledge is extremely unlikely.
Accordingly, it means a lot to demonstrate your ability to create malware should this be of interest. The following is a first aid on everything you really need to know to start writing computer virus:
What makes a virus?
A computer virus is just a piece of code, as was previously stated. However, let's talk about what a virus actually is. Viruses on computers are a particular kind of malware. Any malicious software intended to intentionally harm a computer, server, client, or computer network is referred to as malware. A particular kind of malware known as a computer virus is a computer programme that, when run, replicates itself by altering other programmes and incorporating its code into those programmes. In order to spread, computer viruses typically need a host programme. Understanding the difference is crucial because referring to something as a computer virus only describes how the malware spreads, not its actual purpose. It might be more practical to create malware like a computer worm or trojan that can replicate entirely independent of the host programme.
What knowledge do I require to create a computer virus?
You must first be proficient in coding. Writing a computer virus entails writing a computer programme, which can only be done if you are familiar with a programming language. Python, C/C++, Javascript, and PHP are some of the most used languages for creating malware. Any programming language can be used to create malware, but these are the most widely used in cybersecurity, making it simpler to search for tutorials and courses in these languages than in less common ones.
How to make a virus in real life
You need to know how to package your script as an executable in addition to how to write the code. This way, regardless of the operating system, you can be sure that your application will function. Your malware will only run in a code editor if you keep it in a.py file format. Learning how to disguise your virus as a legitimate file, such as a.pdf,.docx, or.xlsx file, is the final step in packaging your application. The user is more likely to run the programme because it appears to be a legitimate file in this manner.
Third, familiarise yourself with virtual machines, such as VMware Workstations and VirtualBox. This is crucial because you will require a testing environment once you have a prototype of your virus. There's no need to worry about harming your computer or anyone else's when using a virtual machine to see what your virus can do in a controlled setting.

Where can I learn to write my first computer virus?
You can find tutorials online that will teach you how to create your first computer virus. You can use this article's discussion of a keylogger I created in conjunction with the Udemy course as a model for creating your own keylogger as your first malware project by reading the paragraphs that follow. You can find the entire source code right here.
We imported the required libraries as part of the initial development of this programme, and we also created a function that will be used to email keylogger data. It's crucial to remember that for this to function, your Gmail account needs to have an app password. The password you typically use to log in cannot be used for this function. Here is information on creating app passwords.
The keylogger must be set up in the second step so that the data is displayed in a readable manner. The right arrow key, the space bar, the enter key, and other character keys (aside from alphanumeric keys) on the keyboard may appear very differently when the keylogger records them. For instance, you will notice that I have added quotation marks (") around the key "key. Under the "except:" clause, the first statement contains the phrase "space".
The output will be readable when it is emailed to you thanks to these commands.
After the script has been run, you will then create a function that will produce the report every 5 seconds. The strings are only placeholders; you must enter your actual email address and the password for the corresponding app in the send_mail argument.
Our keylogger and reporting function are included in the script's final section. In essence, this is the section of the script that will start the keylogger.
You now have a template for your first ever piece of malware after creating the keylogger! You can check out the Udemy course mentioned earlier or look online for other tutorials on how to write malware if you want to learn step-by-step how to create this and other Python malware.
There are many available, but the trick is to look for tutorials that will build the malware step-by-step and dissect precisely how each component functions. Avoid tutorials that emphasise theory or that only provide you with individual components without assembling them into a functional programme.
