As we move deeper into 2025, cybersecurity is no longer optional — it’s essential. With rising threats like ransomware, phishing, zero-day malware, and data leaks, relying solely on built-in protection may not be enough.
This blog dives deep into a side-by-side comparison of Norton Antivirus and Windows Defender to determine which offers the most effective, well-rounded protection for Windows 11 users.
🔰 Built-In vs Paid Antivirus: What’s the Difference?
Windows Defender (now called Microsoft Defender) is a free, built-in antivirus solution for all Windows 10 and 11 systems. It offers real-time protection, a firewall, device performance monitoring, and ransomware protection. It requires no setup and works out-of-the-box.
However, with Windows 10 reaching end-of-support in 2025, this comparison focuses specifically on Windows 11 users.
Norton Antivirus, on the other hand, is a premium security solution available for Windows, macOS, Android, and iOS. It offers more features, smarter threat detection, faster scans, and additional privacy tools. But does that justify paying for an antivirus when Defender is free?
Let’s break it down with independent tests, real-world malware scans, and a complete feature comparison.
🧪 Malware Detection Tests: Norton vs Windows Defender
✅ AV-Test Lab Results
According to recent tests by AV-Test, a trusted independent lab:
- Both Norton and Windows Defender scored 100% in malware detection for both zero-day threats and known malware.
- Each earned 6 out of 6 scores in performance and usability.
So on paper, they look equally strong — but real-world usage tells a deeper story.
🔍 Real-World Scan Test
A malware test was conducted with 100 malware samples installed on a test system.
- Norton Antivirus:
- Detected: 72 out of 100 threats
- Scan time: 19 minutes
- Low CPU usage — good for multitasking
- Windows Defender:
- Detected: 61 threats
- Slower scan with higher CPU spikes
🔄 Real-Time Protection Test
A second test ran with real-time protection enabled and 50 malware samples:
- Norton detected 46 out of 50 threats
- Windows Defender found 30 threats, with CPU usage spiking up to 100% at times
🔚 Conclusion: Malware Protection
While Windows Defender is decent for a built-in tool, Norton offers stronger, faster, and more efficient protection, especially with real-time scanning.
