If I had w10 I'd use it.
I would not use a msft browser not because it's bad it's a fat target.
Look into something like firefox with the ublock origin add-on.
That does not mean you can you click yes on every download or open every email.
Is it secure enough to rely on Windows Defender for antivirus/anti-malware protection in Windows 10?
Should I be looking for additional antivirus software?
Where can I go for reliable antivirus reviews and recommendations?
