Event Monitor reports Security Essentials real time protection failure for roughly 8 of every 10 system start ups. Does anyone know What the error is and how to stop it? Microsoft Antimalware Event ID 3002 Microsoft Antimalware Real-Time Protection feature has encountered an error and failed. Feature: Behavior Monitoring Error Code: 0x80004005 Error description: Unspecified error Reason: The filter driver requires an up-to-date engine in order to function. You must install the latest definition updates in order to enable real-time protection. The latest version of Security Essentials and the latest definitions for Security Essentials is/are installed. I could go on a rant regarding token attempts to safeguard the Windows Operating System that would make Dennis Miller proud. Fortunately for forum members, that's not what should be posted here.

Are you using the latest virus definitions for MSE?"A programmer is just a tool which converts caffeine into code" CLIP- Stellvertreter http://www.winvistaside.de/

Yes, updated every day. One of the reasons that Win Defender could not be trusted was because it was easily disabled.

I have decided not to pursue this problem any further. A few possibly related posts that I've found, made reference to user rights. I'm certain that many people have worked hard creating Security Essentials and I most certainly could not create such software. However, I think the program should be viewed as a work in progress. Thankyou for trying to help.

Disable the real-time protection for Windows Defender. (turn it off). You have two real-time protection agents conflicting. Defender is not needed when you have another security program installed. MSE is not a work in progress. It has been tested by third parties and passed. Generally, all security applications are a "work in progress" trying to keep up with the malware writers. Sheesh, check out Stuxnet.
