Summary
-
Microsoft Defender has evolved from weak built-in protection to strong one for everyday Windows use.
-
Microsoft published a bold article claiming that Defender was all it needed, then removed it and revised it.
-
Defender covers the basics; Third-party AVs are still useful for advanced features and complex needs.
Microsoft Defender has come a long way since its inception. When it first arrived on our PCs, it was full of holes and people always recommended downloading a third-party antivirus instead of using it. However, Microsoft stuck with it and eventually created something perfectly good for regular Internet use. Now, people from all walks of life had a powerful antivirus running the moment Windows started, which was a huge victory for cybersecurity.
Despite this, using a third-party antivirus is still valid, especially if you want to use advanced features that Microsoft Defender does not offer. However, if a now-deleted Microsoft article is anything to go by, Defender was pretty much the only app you’d need, a stance the software giant has thankfully moved away from.
Microsoft reverses its controversial Defender article
Now he takes a much more reasonable stance
How he saw it neowinMicrosoft has removed an article it published about the usefulness of Defender. Titled “The best antivirus software for 2026: the built-in Windows protection you need,” the article explains how Defender kept Windows machines safe and provides high-quality protection from the first boot.
While I’m certainly not going to argue that Defender is good enough for most users, the stance Microsoft took when talking about third-party antivirus solutions was too strong. This is what it originally said:
Will you still need third-party antivirus in 2026?
For many Windows 11 users, Microsoft Defender Antivirus covers everyday risks without the need for additional software. Whether you choose to add a third-party antivirus depends on how you use your PC and what features you value.
When built-in protection is sufficient:
Windows antivirus protection is usually sufficient when Windows 11 is running with default protections enabled, updates are installed periodically, and software downloads are deliberate. Microsoft Defender Antivirus and SmartScreen already address common threats such as malicious files, phishing sites, and unsafe installers.
When additional tools can help:
You might consider additional security software if you manage multiple devices, share devices with family members, or want services like identity monitoring or parental controls.
Each added tool increases background activity and complexity, so choose tools that fit your actual needs.
The last part is the one that stands out the most to me; It seems that Microsoft is hinting that third-party solutions exist, but they consume computing resources and are difficult to use, making Defender the best choice of all. Which, again, may not be strictly false, but it underestimates what a third-party antivirus can do.
Microsoft has since backtracked on this advice, instead stating that Defender addresses the basics – that there are third-party apps for more complicated matters – and leaving it at that. A much fairer position, in my opinion.
