Virus and Malware Apps

Can anyone tell me the best app for proectting my iphone13 pro max against malware and viruses? I mostly use my phone for browsing the internet and streaming netflix/Amazon Prime Videos and got a message saying my netflix password was in a data breach. I also noticed Netflix was sucking up a bunch of my data.. I have been looking online for the right app that can keep my phone more private and safe from this kind of thing. VPNs are nice and all but half my apps won’t work with it on anyway.. I tried Norton’s app, Macafee, and Total AV and honestly.. all I could see was that they gave me the option of a VPN. I couldn’t tell if it was protecting me from anything.. scanning anything.. maybe I wasn’t using the app right? Can someone PLEASE give me some advice? Which browsers are safest? What should I be looking for?
