What are the Sources of Computer Viruses?

Internet viruses are essentially created by people.

Any skilled coder or a group that invests in viruses can create them.

Most often, they originate from internet sources, such as downloads and installations that are available on your devices.

At the end of the day, there are many different ways and sources for viruses.

This article is for you if you want to understand everything there is to know about computer viruses and how they are created.

Let’s begin straight away!

What is a computer virus?

A malicious software program that secretly loads onto a user’s computer and executes malicious operations is referred to as a computer virus.

No one ever gets a computer virus naturally. They are usually brought on by people. However, since they are produced and dispersed, no one has direct control over how they spread. A virus that has infected a computer attaches itself to another software so that when the host program runs, the virus’s actions are also activated. It has the ability to replicate itself, attaching to other files or programs and infecting them in the process. However, not all computer viruses are harmful.

However, the majority of them carry out malicious acts, like erasing data. Others remain dormant until a specific event (as intended) is started, which triggers their code to run in the computer.

Some viruses cause havoc as soon as their code is executed, while others wait till that event is initiated. When software or documents with viruses are moved from one computer to another over a network, a disk, file-sharing protocols, or through contaminated email attachments, viruses are disseminated.

Different stealth techniques are employed by some viruses to evade detection by anti-virus software. Some viruses, for instance, can infect files without making them larger, while others attempt to avoid detection by terminating the processes connected to antivirus software before they are discovered. When they infect a host file, some classic viruses make certain that the “last changed” date stays the same.

What are the main sources of computer viruses?

Viruses typically attack through four different channels. Even though you frequently use computers, there are still precautions you may take to keep them safe.

Internet

The Internet is a clear source of computer virus acquisition. Precaution should always be taken before downloading any files or documents. Always verify the source, and take extra care with .exe files. In any case, scan all files with antivirus software before downloading.

Email

The next most popular method of getting viruses is through email, after haphazardly downloading things from the Internet. Downloading email attachments that are forwarded to several addresses should be done with caution. When a friend or family member sends you an unusual message, immediately send the email to your spam folder.

External Storage

Although they might not happen as regularly as from the sources indicated above, viruses can nonetheless come through removable storage. Never allow a random person to insert a flash drive into your computer. When they do, have antivirus software scan the files.

Bluetooth

Viruses can also be transmitted via Bluetooth, albeit less frequently than through portable storage. Through a Bluetooth transfer, you could inadvertently introduce a virus to your PC. Once more, the solution is to scan all files obtained through file transfer using antivirus software.

Why do people create Computer Viruses?

Viruses do not naturally exist in cyberspace as I mentioned earlier. It takes a coder to make them. Why do people create them, then? Here are a few reasons for this:

Identity theft

In this case, a virus has infected your computer, recording information from it and sending it back to the virus’s creator or host system. In many situations, the virus sits and observes your online behavior and the data you transfer to the internet, such as credit card information, passwords, or personal identity information, rather than actively searching for data on your computer. Following that, the virus sends the data to the host computer.

To gain Control of Your PC Remotely

In the case of viruses that grant remote access to your computer, this may not always mean full access, but rather that your computer is a slave to the host system, which may transmit commands to your computer to carry out tasks that in some way benefit the virus creator.

For show off

Sometimes, the sole purpose of creating and spreading viruses is to satisfy the virus’s programmer. The hacker will feel more accomplished if more machines become infected with the specific malware. These viruses frequently only offer a nuisance to users in the form of unpleasant pop-up windows or issues using the computer’s operating system.

To harm organizations that compete with them

There are viruses now that can truly harm your computer or that are designed to move from device to device over a network. Once they have taken hold, these viruses look for the operating system and corrupt or delete particular files. Typically, a programmer who infects an organization with one of these viruses has a different agenda than the organization. Although the virus can carry out a wide range of tasks, its main goal is to interfere with an organization’s operations.

Since most organizations send numerous emails internally, these viruses propagate quickly through email. However, in some situations, they can also infect computers outside of the business, causing harm to people who weren’t even the intended targets.
