Welcome to BC LSUZ28FAQs Windows Security Center
Windows Security Center uses a two-tiered approach for detection status. One tier is manual, and the other tier is automatic through Windows Management Instrumentation (WMI). In manual detection mode, Windows Security Center searches for registry keys and files that are provided to Microsoft by independent software manufacturers. These registry keys and files let Windows Security Center detect the status of independent software. In WMI mode, software manufacturers determine their own product status and report that status back to Windows Security Center through a WMI provider.
Windows Security Center will try to tell you about antivirus or firewall programs installed on your computer. However, if a manufacturer decides not to participate, the Security Center will not be able to detect the manufacturer's programs.
It is the responsibility of the anti-virus or firewall vendor to design their software so that it will be recognized by the Windows Security Center. The vendor also must submit the information to Microsoft so the Windows operating system catalog can be updated with the software signature addition.
Sometimes, the Security Center stops recognizing an antivirus or firewall program. Here is one possible solution that may work:
- Click on Start > Run and type: services.msc
- Press OK.
- Click the "Extended tab" at the bottom to view all the info on your services.
- Scroll down the list and find the service called Windows Managament Instrumentation.
- When you find the service, double-click on it or right-click and choose "Properties".
- In the Properties Window > General Tab that opens, click the "Stop" button.
- From the drop-down menu next to "Startup Type", make sure its set to "Automatic".
- Exit and return to your desktop.
- Right click Start and choose Explore.
- Navigate to C:\Windows\system32\wbem\repository
- Delete or rename this subdirectory ONLY.
- Close Windows Explorer when done and reboot your computer.
This will rebuild the deleted folder and the database. Once restarted, Windows Security Center should show the correct information and antivirus/firewall should be recognized.
If that does not resolve the problem, see:
"How to Disable Antivirus Alerts When Security Center Does Not Detect Installed Anti-virus[
"Note: Some Anti-virus programs will disable the Windows Security Center in order to take care of things themselves. For example, when the McAfee Security Center is selected as the default security center, it turns off alerts within the Windows Security Center so that the Windows Security Center will no longer notify you if your firewall and/or antivirus are disabled.
