Microsoft Defender

The built-in free baseline for Windows

Microsoft Defender comes pre-installed on every Windows PC and provides solid baseline protection against malware, phishing, and ransomware. In independent tests, Defender now performs well and is often sufficient for users with cautious browsing habits. However, anyone who needs VPN, password manager, extended web protection, or parental controls should consider a paid suite. As a free reference point, Defender is the most important comparison benchmark.
