May I know your first name, please?

Nice to meet you, *****!
Can you please provide me with a picture of Apple platform security warning?

I found it
It's a simple scam message displayed by malicious websites, trying to trick you into calling the number for help and paying for their “technical support”.
No need to click anywhere.
Just close this website
And the message itself

1. Press the Command + Option + Escape keys simultaneously on your keyboard. This will open the “Force Quit” application window.
2. In the “Force Quit”, click on the browser in which your are seeing the “Apple Platform Security” pop-up.
3. Click the button that says “Force Quit“. This will forcefully end your browser, thus closing the “Apple Platform Security” pop-up.
