Yes, Microsoft Defender can detect and remove malware, but it isn’t a reliable choice for protection against zero-day threats.
During my tests, Microsoft Defender detected 98% of real-time threats. While this may seem outstanding, it pales in comparison to Norton’s 100% zero-day malware detection. Missing 1% of threats is all it takes to infect your PC. It’s also worth noting that Microsoft Defender falsely flagged 5 safe files as malicious, while Norton only flagged genuinely malicious items.
To remain secure at all times, you need to invest in a top-tier antivirus service like Norton. Its constant software updates protect your PC against the newest attacks, automatically quarantining malicious files to keep your data and devices secure.
