Do You Still Need Antivirus or Firewall with Latest Windows or Mac OS?

Introduction:

With the latest versions of Windows and macOS, built-in security features are often enough to protect your system against most common threats. However, the decision to use an antivirus or firewall isn't black and white. This article explores the benefits and drawbacks of using antivirus and firewall programs, especially in the context of the latest operating systems. By the end, you will have a clearer view of whether you still need to rely on these tools or if the built-in security features are sufficient.

Firewall: A Lightweight Solution

Firewalls are essential security tools that monitor and control incoming and outgoing network traffic. Modern operating systems, such as Windows and macOS, come with built-in firewalls that can effectively block unauthorized access while maintaining a low overhead. These built-in firewalls are designed to protect your system from unauthorized access to your network and are recommended for everyday use.

Antivirus: High Overhead, High Protection

Antivirus programs, on the other hand, are more resource-intensive but offer a comprehensive solution against malware and viruses. Although built-in security features are typically sufficient for most users, an extra layer of protection can provide peace of mind, especially for users engaging in high-risk activities like online gaming, filesharing, or visiting dubious websites.

Operating System Security Features

Windows and macOS have evolved to be more secure than ever before. Windows 10, for instance, comes pre-equipped with Microsoft Defender, which provides robust protection against a wide array of threats. Similarly, macOS, known for its Unix heritage and multiuser environment, is inherently resistant to many types of malware.

However, despite these built-in security features, your system's overall security relies heavily on your behavior. If you are diligent in avoiding suspicious websites, files, and downloads, the built-in security might be enough. But if you are interested in online activities that could lead to malicious software infections, having an additional antivirus layer is wise.

Personal Experience: My Journey Without Antivirus

I've personally used the latest versions of Windows and macOS without an antivirus for years. I trust the built-in security features, and so far, I haven't encountered any serious issues. My wife, however, recently made a decision to switch from Norton to the built-in Windows Defender, as she was tired of the recurring auto-renewals. Our email exchange offers insight into the process.

In my wife's case, she does not engage in high-risk online activities. She is cautious with downloads and avoids dubious websites. This makes the built-in security sufficient for her needs. Of course, this experience is anecdotal and may not be representative of everyone's situation.

Protecting Yourself from Online Threats

Although the latest operating systems provide a strong baseline of protection, there are several best practices to follow to ensure the safety of your system:

Keep Your Software Updated: Regular updates not only fix security vulnerabilities but also keep your system running smoothly. Avoid Suspicious Links: Don't click on unknown links or advertisements, and always verify the legitimacy of a webpage before entering any personal information. Disable Unwanted Add-ons: Be cautious about the software you install and read through all dialog boxes carefully to avoid unnecessary or malicious software. Use an Ad-Blocker: An ad-blocker can help prevent the installation of harmful software from ads. Stay Vigilant: Being aware of common techniques used by cybercriminals can prevent you from falling victim to phishing scams or malware.

By following these tips and keeping your system up-to-date, you can significantly reduce the risk of infection from viruses or malware, even without relying on an antivirus program.

Conclusion

While the latest versions of Windows and macOS provide more than adequate protection against most threats, it ultimately comes down to your individual online behavior. If you follow the best security practices and are cautious with your online activities, the built-in security features might be sufficient. However, if you engage in more high-risk activities or simply want an additional layer of protection, an antivirus program can provide peace of mind.
