On my brother's laptop WSC says that no antivirus is installed on his computer, however he has Avast. He also has MBAM and SAS and doesn't have a WSC problem with those two. it happens from time to time and is gone after a while, day or two maybe. Any clue as to why this is happening?

The Security/Action Center gets its data from the Windows Management Instrumentation (WMI) Repository and uses a two-tiered approach for detection status. One tier is manual, and the other tier is automatic through 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.

It is not uncommon for Windows Security Center to sometimes stop recognizing your antivirus (or firewall) and you may need to manually stop and restart it.

Press the WINKEY + R keys on the keyboard or click StartBtn.gif > Run..., and in the Open dialog box, type: cmd
Click OK or press Enter.

If using Vista/Windows 7, click StartBtn.gif and open an elevated Command Prompt by typing cmd into the search box, then right-click on cmd.exe and Run As Administrator. Alternatively, you can go to StartBtn.gif > All Programs > Accessories, right-click Command Prompt, and Run As Administrator.

At the command prompt C:\>_, type the following bolded text, and press Enter after each line:
net stop winmgmt
cd /d %windir%\system32\wbem
ren repository repository.old
net start winmgmt

It may take a few minutes to complete while WMI rebuilds the database. Reboot when done.
