Out of the blue after a reboot today of my laptop, AVAST claims ‘your system is secured’ but WIN7 Action Centre claims that ‘avast! Antivirus reports that it is turned off.’ No matter how many times you click on the ‘Turn on now’ button, this complaint does not go away.
Ideas?
Can you please try a repair of avast and a reboot - repair avast by clicking as to uninstall, when you get the popup scroll to repair.
Have you actually checked that avast is running ?
Check the avastUI, presumably it isn’t indicating Unsecured ?
In the Task Manager there should be avastSvc.exe and avastUI.exe, are they present ?
Yes to having checked AVAST is running. Either it’s running or the best facsimile I’ve ever seen has taken its place.
AvastUI.EXE is running. It claims to be secured.
AvastUI.EXE and AvastSVC.exe both show up in Resource Monitor.
Another shutdown and reboot was apparently sufficient to make the Action Centre complaint go away.
Glad it’s all fixed then 
Yes, that is the reason I asked to check that avast was actually running as the Action Center has form for this type of corruption of its database.
This has been a problem in the Windows Action Center and its father the Windows Security Center for many, many years, but less frequent in the Action Center.
