Microsoft Defender

8.7

/ 10

Microsoft Defender comes pre-installed on every Windows PC and provides solid baseline protection against malware, phishing, and ransomware.

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.
