Action Centre not recognising Avast

Avast Free Antivirus / Premium Security
1

My girlfriend’s laptop is not recognising Avast in the Action Centre. This has happened on my laptop before so i think i already know the answer to resolve this but i just want to check is there any way of fixing this without having to uninstall and reinstall Avast?

Also, what could have caused this problem? She has not performed a system restore or restored her system from a previous backup.

She is using Windows 7 x64

The problem is one of the windows action centers making or rather the wbem WMI database being corrupt. This has been a problem going back as far as win XP.

Whilst these aren’t specifically for win7, any reference to Vista is likely to work in win7.
See http://windowsxp.mvps.org/repairwmi.htm, this also mentions Vista, so that may be valid for win7.
For Windows 7 also see Win7 WMI Repair
Also see http://windowsxp.mvps.org/repairwmi.htm, this also mentions Vista, so that may be valid for win7.

  • OR try
* Click Start, Run and type CMD.EXE
  • Type this command and press Enter:

net stop wscsvc
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
net start wscsvc

EXIT
Reboot

Thanks David i have just solved the problem by clicking turn on Avast Firewall, Internet Security etc then restarting. I didn’t expect that to work as when the problem occured on my laptop that solution did not fix it… I had to uninstall and re-install! Although, i will keep your suggestion in mind if this ever happens again. :slight_smile:

It might just have been enough to reset the WMI database.
