Windows defender not updating wsus

Configuration Manager is never listed in the Fallback Order registry key, as the SCEP client does not recognize a Configuration Manger Software Update Point agent (and associated infrastructure) as a valid definition source and cannot pull definitions from Configuration Manager.The SCEP Client needs to be updated to recognize the SUP as a valid definition source - rather than having to open the Config Mgr Control Panel window, and running a "Software Deployment and Evaluation" cycle.

In other words, just deploying the latest Definition Update for whatever installed Malware Protection Engine would fix these two Nessus alerts 😀 Hands-on!

Currently, the Update button in SCEP does not perform any function when you want to use the SUP as a definition source.

Per: https://support.microsoft.com/en-us/kb/2831244 - When you click Update in the SCEP UI, the client looks for a Fallback Order registry key in HKLM\Software\Policies\Microsoft\Microsoft Antimalware\Signature Updates.

It’s important for Windows Defender to stay up to date so that new known variants of malware can be detected.

This can be achieved if we integrate Windows Defender with WSUS and Windows update, which we’ll show you how to do here in Windows Server 2016.

Nessus actually raised the following two alerts about the Malware Protection Engine in various products: The Nessus database references the issues on these pages: Note Windows Defender may be disabled when Microsoft Security Essentials (MSE) or Forefront Endpoint Protection (FEP) is being installed.

This is by design, as MSE and FEP are functional supersets of Windows Defender.

The client will check each update source in the Fallback Order registry key in the order that they are listed until it locates a source that has available definitions.

If it goes through all sources without detecting available definitions, it returns an error and the update attempt is unsuccessful.

For example, if you want to update from An Electrical Engineer by profession, Kapil is a Microsoft MVP and a Microsoft Content Creator.

Please read the entire post & the comments first & create a system restore point before making any changes to your system.

This window will show the virus and spyware definition versions, as well as when they were last updated.

    However, be sure to carefully check the revision dates on your sheets to make sure there haven't been any changes/updates that you might otherwise overlook!
