I have a late 2013 MacBook Air with latest Dec2019 KIS20 I note that not only do I get frequent freezes of system BUT more importantly it blocks all my browser eg Safari FireFox and Chrome from connection to the internet. This cost me a lot of money one day so ended up uninstalling and IMMEDIATELY solved both freezes and connection via browsers to web. SO at present DONT have any protection. I note that there is a note saying “working on it” from some posting but what do I do about protection in the meantime this is a debacle and tantamount to taking money from customers and offering no solutions? I have the Catalina version 15.3 installed. Everything was fine unto point of install but problem started with freezing and then led to blocking of all browser on line activity and meant that not only did it affect my online university course but also contact with essential http/s:// sites thus HAD to remove protection.
