Q&A for How to Create a Virus

Because some people want to watch the world burn.

To prank a friend maybe. Or maybe you want to get revenge on an old enemy.

Go into the code or just download a spyware detector.

Create a backdoor or an administrator access secured with a strong encryption that will recognize your protocols only. A kill switch is also usable but it doesnt actually "kill" a virus -- it disables/deactivates it until it is newly written with a new code.

Yes, C+ is a high level language that you can use to create any program you would like, such as a virus or Trojan.

By learning some batch programming and performing some basic operations that "might" look like virus ones.

Only when the trigger is present does the virus run. You can make a trigger like this: If the file StopVirusRunning.txt is not present, then run the virus. Keep the virus in the same directory as the file. When you release the virus, don't include the file. If you accidentally remove the file and trigger your virus, then, yes, you'd have a problem.

Probably Python shell or the standard command prompt for your code enlisted in it.

Some people create viruses for educational purposes or humor. Others do it to access sensitive content.

Usually, it is harder to track than normal money transfers, which makes them harder to catch.

A virus won't really "break" your computer, but it can damage your system so much that it renders your computer essentially useless.

Yes, but there are much easier languages to start with! Java would have a broader hit list if it were a more generic type of virus, but would be pretty limited in what it could accomplish.

Probably Python, Bash, or Java. Everyone is different, so one of these might be easier for you than the others, you'll just have to experiment.

C is fairly basic, and probably effective. You don't need to hide your virus, unless you want a better chance of infecting.

Yes, it can. The virus can reformat computer algorithms because using several computer languages, it can communicate with the computer.

Just open Notepad or Notepad++ and begin coding your virus using the steps discussed in the article.

You could simply block the file name, or parse the file itself for known bits of code that are malicious. However, if the virus uses encrypted code, your program should decrypt it first.

This is possible, but do consider that it will be rather tricky to write an effective virus, let alone viruses, without any knowledge in programming, internet resources or not.

It is possible, a Blackberry Z10 supports Android applications that can be possible to install a C+ program in the device.

There's an article all about that here .

Yes, but you will have to implement a listener for the virus to know what you want it to do. For example, have the virus check a shared network folder's contents for a "Listen.txt" and, if found, let it read the contents of that file and execute commands based on what it finds. You will also need to set up port forwarding on his router that forwards the port you are going to be using to his computer; that way you can send commands to his computer from anywhere with an internet connection. Also, I recommend hiding the folder you will be using by setting the folder's attributes to 22. (16 + 4 + 2; 16 is folder, 4 is System, 2 is Hidden). That way, the folder will be invisible.

Try Googling ''hacking for beginners'.' If you have a phone(by any chance, an Android), install a C+ coding app.

No. It is not illegal to make a virus. In most countries, however, it is a criminal offense to distribute the virus, and It is most certainly an offense to distribute a virus that damages a user's software.

It's illegal to release viruses under any circumstances.

It varies based on the language the virus was made in. It's similar to the way viruses affect humans, there is no single medication that will be effective against all illnesses.

No, it's not. Python is slow and requires an interpreter already present on the target PC, and as it not present on most PCs, this will inevitably cause problems. Also, Python source code is visible, which causes it to be easy to identify.

No, this virus is harmless.

It depends. If they made a virus and didn't have a lot of programming experience, then it's unlikely that they will be able to come up with a kill switch or other fix.

Yes, it is. It's called ransomware. These viruses usually ask people to pay for decryption so that they can get their files back.

If you're new to JS and other languages, you should watch a tutorial on it. I found good JS++ and C language tutorials on Khan Academy.
