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.
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.
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:
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.
