Not at all. Any decent security suite isn't going to automatically alter user settings. With Microsoft finally adding a more than sufficient AV into Windows 10 within five to six years there will be a big drop in consumer facing antivirus software, just like there was with firewalls after XP Service Pack 2 helped to kill those. Outside of enterprise environments where hundreds to thousands of endpoints need to be centrally monitored, antivirus software as we know it today is a dying breed.
SMB 1 can be turned back on, but in 2020 there should be no reason to keep a 30+ year old protocol turned on, especially with the security issues it opens up. SMB2 and SMB3 are still well supported, though we'll probably see SMB2 begin to be phased out in ten to fifteen years.
