How To Increase The Installed M.D.A.'s Protection Rates?

Microsoft Defender Antivirus (MDA) protection strength is primarily determined by its configuration and by keeping it fully updated. The context provided only covers how to evaluate and test Defender, not how to tune every setting, so only the following points are supported:

1. MDA is a “next‑generation protection” solution
   • On Windows 10, Windows 11, and Windows Server 2016 or later, MDA includes next‑generation protection features and Microsoft Defender Exploit Guard.
   • These capabilities are what provide the core protection; there is no separate “hidden” Windows setting in the provided context that boosts detection beyond configuring and using these features as designed.
2. Keep Defender fully updated and configured
   • The protection level depends on having current platform, engine, and intelligence (signature) updates. The version numbers shown (like 1.445.445.0) are normal and will change as new intelligence updates are released.
   • The referenced guidance focuses on using Defender’s security settings management to configure and test key protection features. That implies that correct configuration and regular updating are the supported ways to maintain or improve protection.
3. Use Defender’s security settings management for evaluation
   • The article describes “step‑by‑step guidance on how to activate and test the key protection features in Microsoft Defender Antivirus (MDAV) and Microsoft Defender for Endpoint (EG).”
   • Following those steps (for example, enabling and validating next‑generation protection and exploit protection policies) is the supported method to ensure Defender is providing its intended protection level.
4. Handling suspicious or missed detections
   • If a file is suspected to be malicious but not detected, or if a detection seems incorrect, files can be submitted to Microsoft using the sample submission site referenced in the article. This helps improve Defender’s protection over time.

The context does not document additional Microsoft Store tools that increase Defender’s detection rate, nor does it provide any special hidden Windows 11 settings beyond standard Defender configuration and security settings management.
