…chances are you’ll need to discover ways to begin up your Mac in so-called Secure Mode, and to replace from there.

Sarcastically, albeit unavoidably, most third-party safety add-ons don’t begin up in Secure Mode, so an alternate method is just besides up with as many non-security-related apps turned off, in order that they don’t begin routinely if you log in.
You’ll be able to quickly flip off auto-starting background apps within the Settings > Normal > Login Gadgets menu.
