Hello, beginner here, please be kind. I keep hearing that Mac is safe and has no need for real-time scanner, but also that it is needed, but apps for that are... bad. I heard Norton is very bad? Are Avira, Avast, AVG or Sophos bad for Mac health? Among free apps I keep seeing only Malwarebytes that is considered good. I download apps only from App Shop or from known pages (like VLC player). I don't go to suspicious sites, but save images from boards (sometimes gif and webm) and I surf places like Tumblr for pics and cat videos (downloading mp4s sometimes from tumblr's server). With lifestyle like this, is there an app I need? Is there any real time protection against potential shitware and trojans? Or are all those realtimers harmful towards Mac? Would I be secure if I simply run Malwarebytes every day to see if something slipped in?
