Vista Security Center error message

[NSA_CIA]

hi,
I have the following setting :
Firewall "Active"
Automatic Updates "Active"
Antivirus "Not Found"
i have problem Windows Security Alert always display "Virus Protection Not Found". what does it mean? Windows Security Center recognized my virus software "Avast 4.8".A uninstalling Avast and installing FreeAV9 brought no change. So I reinstalled Avast. I have no other software installed and no external USB-Stick is used. What has happened and what is the solution?Can anyone help!!!

go to services.msc..

and find Security Center.

right click it and then open "properties". select "automatic" instead of "disable".

then again go back to security center, and turn it on.

Click Start, Run and type CMD.EXE

Note: In Windows Vista, you need to open an elevated Command Prompt window. To do so, click Start, click All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

Type this command and press Enter:

net stop winmgmt

Using Windows Explorer, rename the folder %windir%\System32\Wbem\Repository. (For example, %windir%\System32\Wbem\Repository_bad). %windir% represents the path to the Windows directory, which is typically C:\Windows.

Switch to Command Prompt window, and type the following and press ENTER after each line:

net start winmgmt

EXIT

hi,
try to stop avast and then restart it again ,this can be done via icon which is next to Windows clock. That should fix the problem.
