Windows 10: Windows Security showing random alert!

What is this message that windows security is showing. It started to happen after the recent update of Windows 11.

Random Security Alert from cloudflare-dns.com?

I have absolutely no idea what this is, but I keep getting a security alert pop up in the background every minute or so, and when I click for more details it says the certificate is intended to ensure the identity of a remote computer from cloudflare-dns.com. I don't know what that is and Google hasn't been particularly helpful so far. Any help is appreciated.

Windows version 1809

Emergency Alerts

Hi Stephanie,

Just to confirm, is this the same thing that you tried on your phone, in order to turn off Amber Alerts?

• Open Settings.
• Tap on System.
• Tap on Messaging.
• Tap on the Change emergency alert settings link.
• Turn on or off the emergency alerts you want.

Let us know if this was the same thing that you tried.

We would also suggest to reset your phone after doing these steps to ensure that the changes on your phone's settings will be refreshed.

Simply press and hold the Power and Volume down button for 15 seconds and then release your hold afterwards.
