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.

Microsoft Defender vs Malwarebytes
Microsoft Defender and Malwarebytes compared side by side: protection, performance, pricing, and features. Which antivirus suits you better?
Malwarebytes has built its reputation as a specialist in malware detection and removal. The Premium version offers real-time protection against malware, ransomware, and malicious websites. The software is particularly lightweight and works well as a complement or replacement for heavyweight suites. The VPN add-on provides extra privacy. The feature set is intentionally focused – those looking for extras like password managers or parental controls will need to look elsewhere.
