"Thank you for your reply, however I am not able to find any security apps that I have not already removed. Where or how should I be looking for said apps?"
-------
A. Finding These:
Did you use an uninstaller? If not, but rather dragged the icon to the trash, then caches and all other junk files form these apps are all laying about your Mac. So, likely, you'd have to reinstall all the software, and then uninstall each using an uninstaller. Ask the developer(s) of these software apps where to go from there. As fro which files they are, I'm not so certain there is a discrepancy between two or more of the same-named files.
B. Restore form a Time Machine Backup:
- Did you recently create a backup of your Mac prior to all of this? IF so, restore from that, and all would be fine.
Are you Concerned of Losing Data?:
- If not, just move ahead and erase the disk and then install the macOS.
- If so, then first backup your macOS.
Backing Up the Mac: Start by creating a Time Machine backup of your Mac, so that you can have something to restore your Mac from, should anything go wrong with the reinstall. Go Here: Back up your Mac with Time Machine - Apple Support
