From what I gather by looking at the pics...
You used Tracker Control (Slim? I was not aware of that version, but for different devices there may be different versions. Hopefully the features are the same.) to see details of certain system apps.
You can tap on those individual items, and block each one individually.
This can and will 'break' some apps.
It can be very frustrating to keep a device working, because you will find yourself playing 'Wack A Mole' going back and forth to Tracker Control to allow or disallow some tracker or other.
With what I do online, Tracker Control says that I have over a hundred trackers in my browser.
This is not so- but the websites I visit DO have trackers- many/most of all sites do.
Tracker Control sees this, and reports it as trackers found in my browser.
(My browser blocks trackers, but I have to allow these in Tracker Control in order for those sites to work. It is this type of thing that keeps me from using Tracker Control.)
As for the apps in the pics, Root is on one of my devices as well, so I would not be pressed about that.
The same goes for the other system apps, as it would be difficult for someone to install something nefarious there even if the device was in their hands- and near impossible to do so remotely.
So, back to the McAfie app- do you see all of the Google junk that is buried inside that app?
That is all spyware.
Legal, legitimate spyware.
It is how the app is provided to you for free.
And it is the same for any app that has those analytics and Admobs and the rest.
That is why it is best to avoid any app that has that crap- and the vast majority of apps on the Play Store have that crap.
Isn't it funny (no, it isn't funny at all) that Google warns us over and over again to only get apps from them for our 'safety', yet they are the ones doing the majority of the spying?
Anyway, here is yet another app that will tell you what apps have what permissions and other things on your device, and give more details as to what those permissions and other things actually mean to you.
Once again, (yes, I understand that we are basically strangers and that I am asking you to download and install a lot of stuff) this is a small, simple app that I put on all of my devices.

Now, did I run through how to find 'secret' apps on a device?
I can't remember if I did, but it is not real difficult.
By 'secret', I mean apps that do not show up in your app drawer.
When I first started on my Android journey, I tried to download something from some poop site, and evidently at some point it had me download and install (or it just did that on its own, IDK) something else.
Yadda, yadda, yadda, I wound up uninstalling the app anyway.
Well, whatever else had been downloaded and installed did not get uninstalled, and I was getting ads that I should not be getting- because I uninstalled the app (because of the damn ads!)
So began my detective work, even as unskilled as I was.
After a long bit, I figured it out.
In my apps list there was an 'app' all the way at the bottom of the list that I did not recognize.
It had no name, no icon (so it would not show up in my app drawer!), but there it was taking up a bit of space and using data.
NoRoot actually clued me into its existance, I believe, as it showed up in the apps list there and also in the log of internet access.
Because the log gives the time of access, and I knew when I saw the last ad, BAM! I had my culprit.
But with no icon or name, the app was tricky to find to be rid of.
Settings
Apps
(show all apps)
(show system)
scroll to the bottom and look for anything that has no icon and no name.
Clear data first (very important), and then uninstall.
Clearing data first before uninstalling ensures that any files/folders of that app are gone along with the app itself.
On another occasion, I uninstalled an ad ladden app and the ads continued on and on- until I found the folder and files that did not get uninstalled with the app.
So clear all data first, with any app you are going to uninstall.
So, back on point-
let me know how it goes, and if the device perfornance improves, degrades, or stays the same.
