two pop ups appeared. One from “Macso-supp-action.com”

Received two pop ups on a new tab when trying to update a Microsoft password.

“Pop up macso-supp-action.com says

Attention!

MacOS Security Center has identified that your system is under threat. Please scan your MacOS as soon as possible to avoid more damage.

Don’t leave this page until you have undertaken all the suggested steps by authorised Antivirus.”

A second Security Alert pop up on same page says:

”You have just visited multiple infected websites

Your MacOS is at risk of being infected by viruses

To continue browsing safely - click Scan below to run Antivirus”

I assume these are scams and I should delete the tab. I have Norton Antivirus and this doesn’t appear to be connected. Do I have something going on that does need to be checked?
