Since the first nefarious self-copying software was released in 1986, computer viruses have been making your computers and devices sick. Some of them could brick your devices, while others can cause a slowdown or even steal your data. However, most of the time you can wipe a virus from your device if you act fast.

A virus is a type of piece or programming that, similar to a flu virus, is able to reproduce itself by attaching itself to files and programs and infecting them. Then, it makes copies of itself. Once the virus is infected by an application, it could spread to other programs and devices that are connected to the same network. These viruses can cause a variety of damage. They can steal passwords and credit cards or erase data, corrupt software, or even take over your entire system.

Viruses can spread from one computer to the next via text and email attachments. They may also spread via Internet file downloads or social media scams. They can also infect smartphones and mobile devices by being hidden within shady app downloads. Some viruses are playful in both intent and effect while others were created with the intention of generating money.

In the majority of countries, creating and propagating computer viruses is considered a crime. If you’re interested in learning how to create a virus, you can do it with Notepad and other tools. It’s not for the faint of heart however, it’s an interesting way to test your coding abilities. You’ll need to determine how your virus will behave after it has infected the system. This can be anything from displaying a warning message to deletion of data or causing corruption or even contacting the contact lists of your friends.
