I saw from a 2021 post that this pop-up is a scam. It reads: Apple Platform Security” and “ACCESS TO THIS PC HAS BEEN BLOCKED FOR SECURITY REASONS.” Because the reply with the fix is old, I wondered if there’s a new way rid it from my laptop.

No one, not even Apple, can "see" what is on your computer without your giving express permission for remote access.
If a specific web site did this to you, do Safari Preferences, then click the "Websites" tab. Choose "Notifications" from the left-hand pane and see if any sites you do not recognize show in the main pane:
If so, use the "Remove" button to delete the listing.
Yes they are scams. Most likely in a webpage. You should be able to close the window and open up another Safari window. Restarting the computer is another option. Either provide a screen shot or explain what steps do not work to make it go away. Obviously do not call any numbers provided for assistance.
Thank you, Allan for your quick response with screenshot. I followed your directions, but the offending website, which was UHC insurance company for teachers, did not appear in the main pane. The company was breached in 2023. Perhaps this issue is connected. I’ll follow Mac Jim’s advice and see what happens. Thanks again.
Thanks, Mac Jim. I simply opened another Safari page, then quit. The bogus security warning miraculously disappeared. As stated in Allan’s response, the website was a healthcare site. I’ll make sure I didn’t misspell the address.
