My Windows Defender is currently switched off, because my Nortons is doing its job instead. Likely my Nortons switched my Windows Defender off.

Is Windows 11 affected by this bug?

You mean "Is Poser 11 affected by this bug?" The answer to that is "No." Poser 11 does not use Adobe Flash or Air. Poser 10, Poser 2014, and several earlier versions do use Adobe Flash, and that is why they are affected.

According to a PC World article I read, Windows Defender is the best overall protection available for Windows 10. As updates for Windows 10 are automatic and come in quite often, I would look into the effects of interaction between Windows Defender and Norton if I were you. It pays to know what is really happening, rather than hazarding a guess.

In my own experience I found that most different makes of protection software normally conflict with each other, even to the point of treating the others as malware. One that plays nice with most others is the aforementioned Malwarebytes (recommended). With Windows Defender and Malwarebytes, you should have really great protection.
