What is a Cyber Virus?

One of the most frequently asked questions about cybersecurity in today’s digital world is, “What is a cyber virus?” You may have encountered a computer virus if your computer has suddenly slowed down, files have disappeared, or strange software has started running without permission.

A cybervirus, just like a biological disease that causes sickness, is a piece of malicious computer software that sneaks onto your computer and spreads. It then damages it. This is more than a nuisance. It can steal data, delete important files, and allow hackers to take control of your system.

This article will explain everything you need to know about cyber viruses using everyday language. We will explore types and spread of cyber-viruses as well as real-life examples of such viruses.

How to explain a Cyber Virus?

A cybervirus is a computer program that was created to disrupt computers, steal data, or cause harm. The virus attaches to other files or programs and spreads through the sharing or execution of those files. Kaspersky claims that viruses can operate secretly and without user knowledge.

Imagine it as if a hitchhiker sneaks into your vehicle without permission. You may not even notice at first. They may steal your items, drain your fuel, or damage your engine.

A deeper look at Cyber Viruses – Wikipedia

According to Wikipedia’s definition of a virus, it is a malware that self-replicates by inserting code into other programs. The virus will spread every time the infected software is run.

This definition emphasizes the following:

1. To spread, a virus requires a host program.

2. It is difficult to stop it without anti-virus software because it can automatically replicate.

What are Cyber Viruses and Their Types?

Like doctors classify biological virus types, cybersecurity experts also classify computer viruses according to how they spread and what damage they do. Here are some of the most common types.

1. Boot Sector Virus

It attacks the portion of your computer that loads the operating system. It is spread by infected flash drives.

2. File Infector Virus

This type injects malicious code into system files. The virus is executed every time the file is run.

3. Macro Virus

This virus is common in older versions of Microsoft Office files. It activates when the document is opened.

4. PA polymorphic virus

is designed to change its code constantly to make it harder to detect by antivirus software.

5. Browser Hijacker

This virus alters your browser’s home page and redirects you to malicious websites.

Experts estimate that there are over ten types of computer viruses.

What is a Cyber Virus?

The ILOVEYOU Virus is a famous example. In 2000, it spread through emails that looked like a love note. The file was overwritten when people opened it, and the virus spread to all their contacts.

Stuxnet is another well-known example. It targeted industrial systems and is often mentioned in cybersecurity case studies.

The following examples demonstrate why the virus and threat protection are essential.

Computer Virus Symptoms

How can you tell whether your system is infected or not? Look out for these symptoms that indicate a virus.

• Your computer will become very slow.

• Popup ads are displayed frequently.

• The files are corrupted or missing.

• Your homepage is changing without your permission.

A Guide to Preventing Computer Viruses: Step-by-Step

This is true both for cybersecurity and health. Here is a guide on how to prevent computer viruses.

Install Antivirus Software

Use trustworthy tools such as Norton Antivirus or McAfee.

Step 2 – Keep your system updated

Update Windows or macOS regularly to patch security holes.

Step 3: Enable Firewall

Your firewall is like a security officer that blocks unauthorized access.

Step 4: Beware of suspicious emails

Never download files or click on links from an unknown sender.

Step 5: Use Strong Passwords & MFA

Use complex passwords and enable multi-factor authentication (MFA). Multi-factor authentication (MFA) is enabled when you use complex passwords.

Step 6: Back Up Your Data

Back up your files regularly using cloud services such as Google Drive and external storage.

Five types of computer viruses explained

Here are the 5 most common types of computer viruses that you should know:

1. File Infector Virus

2. Macro Virus

3. Browser Hijacker

4. Polymorphic virus

5. Resident Virus

Malware vs Computer Viruses

Malware is often confused with computer viruses.

• Malware refers to all malicious software, including viruses, worms, and trojans. It also includes spyware and ransomware.

• A virus is just a type of malware that spreads itself by attaching to other files.

Think of viruses as one member of the family of malware.

Why Virus & Threat Protection is Important

Most people don’t think about security until after they have been attacked. By then, however, it is too late. By investing in good threat and virus protection, you can not only protect your data but also your finances, reputation, and privacy.

Modern tools such as endpoint security software and VPNs will give you the confidence and peace of mind to work, browse, and shop online without fear.

Investing in a good antivirus product today can give you peace of mind.
