On Windows 10, if you’ve ran CCleaner, then you’ll notice an icon in the notification area alerting you on hover over with a message: ‘PC status: Potentially unprotected’, when you click on it, Windows Defender opens and shows the same message with the information ‘You haven’t run a scan on your PC for a while. This could put your PC at risk’.
This icon in the system tray nags you and won’t go away until you perform a scan, temporary solution then would be to do a Quick scan, after that, to don’t get it in the future again, you’ve to do this.
In Windows 10, Fix Windows Defender’s PC status is Potentially unprotected warning
Open CCleaner, click on ‘Applications’ tab, scroll down to ‘Utilities’ and uncheck ‘Windows Defender’ (check the screenshot below). That’s it! You won’t get this notification error in the future.
What happened here is CCleaner has deleted the scan logs of Windows defender, as a result, Microsoft built-in antivirus thinks you have not performed a scan since long time and triggers that warning.
Have you experienced this?How you’ve solved it then?
Many thanks for solving this nagging problem for me.
Makes sense, thank you for simple explanation and resolution.
