Microsoft Defender vs Trend Micro

Microsoft Defender and Trend Micro compared side by side: protection, performance, pricing, and features. Which antivirus suits you better?

Microsoft Defender

8.7

/ 10

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.

/ 10

Trend Micro Maximum Security offers particularly strong protection against phishing, fraudulent websites, and email threats. The suite includes a powerful web filter, privacy scanner, and optional parental controls. The interface is straightforward and suits less tech-savvy users well. Performance is solid, though not the lightest on the market. An interesting choice for seniors and families who spend a lot of time online.
