[macOS Big Sur Getting an Error "System extension required for Web and Email Protection was not started because of error. Try to restart macOS or reinstall the product"]

Until we get a proper update I just use Firefox in a WIn10 VM via Parallels.  At least Nod32 is working in Windows10 so there is protection there.  Is this the most convenient way, no but it's the safest until this nonsense gets figured out.  I am not messing with any VPN to get Eset to work.

It's not like Apple to all of a sudden update an OS.  Eset should have had plenty of time to update their product to be Big Sur compatible.  No excuses!.

I am having the exact problem.  I uninstalled and reinstalled to the latest version.  There is no problem until the first reboot then I get the same error as the original poster.  I did submit a tech support request and hopefully they have a fix soon.
