Overview
- Microsoft’s new guidance says most Windows 11 PCs do not need extra antivirus beyond Microsoft Defender when default settings stay on.
- Defender is part of Windows 11, turns on by itself at setup, ties into the operating system, and updates all the time to block malicious files and phishing links.
- Microsoft notes some people may still want third-party tools for managing many devices, shared family PCs, identity monitoring, parental controls, or corporate policy and threat tracking.
- The company warns that adding more real-time scanners can slow a PC, use extra RAM and CPU, and create conflicts, so users should run only one real-time antivirus.
- Reviewers continue to test and recommend paid suites for added features, even as coverage from outlets like Forbes and PCWorld report Microsoft’s stance that Defender now covers everyday risks for typical users.
