I just upgraded to High Sierra and started getting these System Extension Blocked error messages from my antivirus. I see that there is supposed to be an option to Allow this via System Prefs->Security and Privacy but I never see the "Allow" button. Re-installing the antivirus software didn't help. Any ideas?
