The 10 most common ways that computer viruses are contracted

It’s estimated that there are well over one million unique strains of malware in existence today, and that number is growing rapidly. So it’s no surprise that many people are confused about how these malicious programs find their way onto our computers in the first place. Here are ten of the most common ways that computer viruses are contracted:

1. Email attachments

One of the most common ways that viruses are spread is through email attachments. malicious code can be hidden in seemingly innocuous files like images, PDFs, and even executables. Often, these files will be masquerading as something else entirely, like a bill or invoice. When the unsuspecting recipient opens the attachment, the virus is unleashed.

2. Downloading infected files

Another common way that viruses make their way onto our computers is by downloading infected files from the internet. This can happen either knowingly or unknowingly. For example, you may download an infected email attachment from a phishing email, or you may unknowingly download an infected file while visiting a malicious website.

3. Drive-by downloads

Drive-by downloads occur when you visit a website that has been infected with malicious code. This code can automatically download and install itself onto your computer without you ever knowing. This is often used in conjunction with other methods, like email attachments and downloads, to further spread the virus.

4. Infected websites

Infected websites are another common way that viruses spread. Similar to drive-by downloads, visiting an infected website can cause malicious code to be automatically downloaded and installed onto your computer. However, this can also happen if you simply click on a link that takes you to an infected website.

5. Removable media

Any type of removable media, such as USB flash drives, CDs, and DVDs, can potentially be infected with a virus. If you insert an infected piece of removable media into your computer, the virus can be automatically installed and run. This is why it’s important to be careful about what removable media you insert into your computer.

6. Network shares

If you’re connected to a network, such as at work or school, you may be able to contract a virus by accessing an infected network share. This is a shared folder or drive that contains infected files. If you access these infected files, the virus can be automatically installed onto your computer.

7. Botnets

A botnet is a network of infected computers that are under the control of a malicious actor. These computers can be used to spread viruses and other malware to other computers on the internet. Often, botnets are used to launch large-scale attacks, like Distributed Denial of Service (DDoS) attacks.

8. Peerto-peer (P2P) file sharing

Peerto-peer (P2P) file sharing is a popular way to share music, movies, and other files online. However, it’s also a popular way to spread viruses. This is because infected files can be shared among users of the P2P network. If you download an infected file, the virus can be automatically installed on your computer.

9. Malicious ads

Another common way that viruses spread is through malicious ads. These are ads that contain malicious code that can automatically download and install itself onto your computer. Often, these ads are displayed on websites that you visit. However, they can also be displayed in email messages and other locations.

10. Social engineering

Social engineering is a term that refers to various methods that attackers use to trick people into doing something that they wouldn’t normally do. For example, an attacker may send you an email that appears to be from your bank. The email may contain a link that takes you to a malicious website that steals your information. Or, an attacker may trick you into downloading and installing an infected file.

These are just a few of the most common ways that computer viruses are contracted. However, it’s important to remember that new ways are always being developed. So it’s important to be vigilant and take precautions to protect yourself..View it
