Computer Viruses: What are they and do I need to be concerned?

Staying Safe Online: Understanding Computer Viruses and Protecting Yourself

The internet offers endless possibilities for connection, information, and entertainment. However, navigating the online world also comes with risks, and understanding computer viruses is crucial for protecting yourself and your data.

What is a Computer Virus?

Think of a computer virus as a malicious program that can spread from one device to another. It can attach itself to other programs or files on your computer, modifying them and potentially causing harm.

Imagine your computer is like your house. Computer viruses are like nasty little bugs that can sneak into your house and cause trouble. They can hide in emails, pictures you download from the internet, or even a USB stick you plug in.

How Do Computer Viruses Work?

Viruses typically spread through various ways, including:

• Email attachments: Clicking on an infected attachment can unleash the virus onto your system.
  ‍
• Malicious links: Clicking links in emails, messages, or websites can download the virus if they lead to compromised websites.
  ‍
• Downloaded files: Downloading files from untrusted sources, like peer-to-peer (P2P) networks, can be risky, as they might contain hidden viruses.
  ‍
• Infected USB drives: Inserting an infected USB drive into your computer can transfer the virus.

Once a virus infects your computer, it can perform various harmful activities, such as:

• Stealing personal information: Viruses can steal your passwords, credit card details, and other sensitive data.
  ‍
• Damaging files: Some viruses can corrupt or delete your important files, photos, and documents.
  ‍
• Spreading spam: Infected computers can be used to send out spam emails to your contacts, unknowingly putting them at risk too.
  ‍
• Slowing down your computer: Viruses can consume system resources, making your computer sluggish and unresponsive.

Are Viruses Still a Problem Today?

While advancements in hardware and software security have made it harder for viruses to infiltrate systems, they remain a threat. Cybercriminals constantly develop new and sophisticated viruses, exploiting vulnerabilities in software and human behavior. However, it's important to understand that they're less prevalent compared to the early 2010s. Back then, major virus campaigns caused significant damage.

Why are viruses less common today?

Several factors contribute to this decline:

• Advanced antivirus software: Antivirus programs have seen tremendous improvement. They offer better detection rates, additional features, and overall improved performance compared to their early 2000s counterparts. Most devices are built with built in virus protection.
  ‍
• Limited capabilities of viruses: Viruses are typically small and simple programs. This limits their ability to evade sophisticated defenses and perform complex actions.

Do I Need Antivirus Protection?

What exactly is Anti-Virus Software?

Antivirus software: Offers real-time protection by scanning files and programs for viruses and removing them. This can be particularly helpful if you frequently download files from various sources or click on links in emails.

Do I need it?

It depends on your individual needs. Most devices these days include virus protection which means for most people they do not need another third party protection. However, while virus threats are significantly reduced, they still can remain a threat depending on your online activities.

And while antivirus software can add an extra layer of security, it's crucial to note that it's not the sole defense against cyber threats.
