Ok, I made a huge mistake: I put Norton onto my mac and now I cannot get rid of it!
System: macOS Catalina 10.15.7
I tried:
- Drag app icons to trash and select "uninstall"
- Run Norton's utility here (https://support.norton.com/sp/en/us/home/current/solutions/kb20080427024142EN)
- Using Terminal, I did the following:
a) I had to give it Full Disk Access first
b) $ sudo find / -name "norton" >> norton.txt
I was able to get rid of everything in the norton.txt file, but when I rerun find I get "Operation not permitted" for a lot of files & directories in "/private/var/folders" and "/System/Volumes/Data/"
I know Norton isn't fully removed because each time I try to install Avast it tells me:
"Norton Internet Security has been detected. To install the Avast product, please uninstall the incompatible software first."
(I posted this in StackOverflow but they suggested I try over here)
(I see a similar question here: How do I remove kext files after uninstalling Norton Antivirus on mac to then install Avast? but I am not sure if I am able to unload the kext files because my Find command may not even find them yet!)
Best Answer
It turns out I needed to disable System Integrity Protection first and then find and remove the offending files.
