Like you, @Sitting- , I browse to lots of places on the Internet. I only use Defender because there is no one more qualified to protect the operating system than the operating system author itself. The article I posted a link to further links out to other articles which, in total, illustrates the frustration browser authors experience at the hand of AV vendors that step in and disable the protection mechanisms they have baked into their browsers. This increases the attack surface available to cybercriminals.
With headlines like "Symantec calls antivirus 'doomed' as security giants fight for survival," and Google browser engineers tweeting out "You misunderstand your own ignorance. AV is my single biggest impediment to shipping a secure browser," I'm inclined to stop throwing good money after bad.
YMMV. Everyone is always free to spend whatever they like on AV. As always, your money, your choice.
