@Thorn-Rose67 sorry for such a late response, but you can probably turn off notifications from that site. Assuming the Brower is Google Chrome, go to settings, privacy and security/site settings, notifications, and find the website it takes you to. On my chromebook, there are three dots next to the site, and if you press them, you can block notifications from that site. I'm not sure what to do on a phone.
If you ignore it, I think nothing will happen. Its probably a scam if it takes you to a non norton.com website
