Microsoft Defender

Microsoft Defender is the built-in security solution for Windows. It has improved significantly over the years and now provides solid, baseline protection against malware, ransomware, and phishing. It is completely free, integrated into the OS, and requires no setup. While it is sufficient for the average user who practices safe browsing habits, it often lacks the advanced heuristic and behavioral analysis found in dedicated third-party suites. It is a great starting point, but for users who handle sensitive data or frequently download files, a secondary, specialized tool is recommended.

Microsoft Defender scores 6.2/10 (Fair) on Lunoo, making it rated in the Malware Removal category.
