i got a notice that my phone was this a scam?

You probably saw that notification while using Safari and surfing through a website. Yes, that was a scam and the notification was attempting to scam you into some type of a purchase for iPhone protection.

All such messages are scams presented by criminals. Close the offending page and avoid sites that are involved in such bogus advertising tactics.

Or worse. Give your credit card or bank account details to "phishing" criminals, and for all you know, they won't be satisfied merely with billing you the normal price for some supposed anti-virus application.

They'll help themselves to much larger amounts.
