I use Objective-See's free and open-source BlockBlock:

https://objective-see.com/products/blockblock.html

It picks up background daemon tasks that suddenly are created and allows you to block them immediately. That's certainly one major way to pick up and block hidden malware on your computer.

All of the tools by this guy are incredible, they are also recommended, e.g. tools to pick up and allow you to block access to microphone or camera.

... and definitely read objective-see's blog post from time to time if you are into security topics. The malware take-apart documentation is extremely enlightening.

(Intereseting fact: A lot of malware quits immediately if Little Snitch is installed. So running Little Snitch alone prevents some malware from infecting your system)
