Hot Take Microsoft quietly reveals whether you need a third-party antivirus software in Windows 11

So, according to the Microsoft article, I must use this chain to be secure? For instance, if I use Firefox rather than Microsoft Edge, am I not secure, or is it better to use a third-party antivirus program?

When using Firefox, you miss SmartScreen. However, you may use a browser extension like Malwarebytes Browser Guard or a similar one.
Another problem is "Block at First Sight," which is not supported in Firefox. But, this is mainly covered by SmartScreen for Explorer.
Generally, the advantage of third-party AV is when you do not like/respect SmartScreen for Explorer.
 
Microsoft as a company is one of the worst there is. I never trust their products. Whatever they do. Despite being the second most expensive company on earth, its customer service and its Windows system are terrible.
ok, so are you a linux user or a macOS user (or some other OS?)... just curious. One time MS support actually helped me! but I am using linux more and more, like right now, and my Apple mini too...

I use Windows because I have no other alternative, Linux doesn't work for me. And I think many of us use it out of obligation, not out of pleasure.
 
Microsoft no longer claims that Windows 11 has all the protection that you need
