{"slug":"norton-vs-windows-defender","title":"Norton vs Windows Defender","url":"https://www.aversusb.net/compare/norton-vs-windows-defender","faqCount":5,"faqs":[{"question":"Is Windows Defender good enough in 2026?","answer":"Yes, Windows Defender is sufficient for most users. According to 2024 AV-Comparatives testing, it achieves a 97.2% real-world malware detection rate with minimal false positives. It's best paired with good browsing habits and regular software updates. However, users handling sensitive data or managing multiple devices should consider supplemental tools like Norton."},{"question":"How much does Norton slow down your computer?","answer":"Norton causes approximately 9-12% system slowdown during full system scans, compared to Windows Defender's 2-4% impact. For everyday browsing and file operations, the difference is less noticeable. Norton has improved performance in recent versions, but it remains heavier than the built-in Windows solution."},{"question":"Does Norton's VPN really work?","answer":"Norton's VPN is functional but limited. The base plan includes 500MB per day, which is sufficient for light browsing. Norton's higher-tier plans offer unlimited VPN access. Independent testing shows it provides adequate encryption and privacy, though dedicated VPN providers like ExpressVPN offer more robust features and higher speeds."},{"question":"What happens if I remove Norton and just use Windows Defender?","answer":"You'll save $39.99 annually and recover 9-12% system performance, with only a minor 1.3% decrease in malware detection (97.2% vs 98.5%). You'll lose VPN, password manager, and dark web monitoring. This is a reasonable trade-off for casual users, but professionals handling sensitive data should keep additional protection."},{"question":"Can I use Windows Defender and Norton together?","answer":"It's not recommended. Running two active antivirus engines simultaneously causes significant system slowdown and can trigger false alarms from each scanning the other's files. Choose one or the other. If using Norton, disable Windows Defender's real-time protection and rely on Norton exclusively."}],"faqPageSchema":{"@context":"https://schema.org","@type":"FAQPage","@id":"https://www.aversusb.net/compare/norton-vs-windows-defender#faq","url":"https://www.aversusb.net/compare/norton-vs-windows-defender","inLanguage":"en-US","name":"Norton vs Windows Defender — FAQ","description":"Frequently asked questions about Norton vs Windows Defender","dateModified":"2026-06-21T15:55:54.511Z","author":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"publisher":{"@type":"Organization","@id":"https://www.aversusb.net/#organization","name":"A Versus B"},"isPartOf":{"@type":"Article","@id":"https://www.aversusb.net/compare/norton-vs-windows-defender#article"},"license":"https://creativecommons.org/licenses/by/4.0/","speakable":{"@type":"SpeakableSpecification","cssSelector":["#faq",".faq-item"]},"mainEntity":[{"@type":"Question","name":"Is Windows Defender good enough in 2026?","acceptedAnswer":{"@type":"Answer","text":"Yes, Windows Defender is sufficient for most users.
