"legacyLoader-x86_64 (System Preferences)"

When I go to try to do certain things on my MacBook, instead of asking for an admin account and password it asks me to allow "legacyLoader-x86_64 (System Preferences)" to do things. I only see this when I'm trying to use a firewall like program from my internet provider but cannot find anything online to see if this is a normal function or name. Does anyone have any insight as to why this pops up? I have had severe issues with having my devices spied on and I want to make sure this is not the case. Thanks in advance to any replies!

MacBook Pro 15″, macOS 12.4

That legacyLoader is a normal part of macOS. Some installed app is trying to present a preferences pane in System Preferences, and that loader is how the preference pane display is implemented.

If you do not trust your current macOS install, wipe and reload, and with new passwords everywhere,

I’d also generally suggest removing the add-on firewall, and using what is built in:

Which firewall? The built in ones, or some add-on?

What has already been recommended, what of that have you implemented, and what happened?

Download and run EtreCheck, and share the report to the clipboard. Then open a new reply here, and press the Additional Text button that looks like a printed page, and paste the hardware and software configuration report here. That’ll get us a baseline for the current configuration.

I have had a strange issue with my firewall. Every once in a while it will suddenly be turned off without me doing so. I don't know what causes this but I also had an apple technician viewing my MacBook remotely when I got locked out of my iPhone and was having issues and at that time the firewall was on "blocking all incoming connections." He said with this on he shouldn't have even been able to view my MacBook remotely. Is this true? And is there any means by which a firewall could potentially be turned off remotely, turn off by itself, or otherwise any means other than physically accessing the MacBook itself? I have had serious issues for several years now with my security.
