"The pop-up that you see is one of the features of our application.
When the application is used, it secures your device from MITM (Man-In-The-Middle) vulnerabilities by always validating if traffic on your device is using our certificates.
If any other applications try to generate traffic on your device, our application will see their certificate and ask you if you trust it before allowing anything to happen.
Additionally, the same verification process is used if a certificate is present on the system due to the network that is being used.
That being said, if you trust the certificate that is mentioned in the pop-up, please select the Trust option to continue using the NordVPN application.
Let us know if you have any further questions. "
