Cannot turn off "Background Items Added" Notifications

Here are the locations to check:

• Go to Finder > Go > Go to Folder. Paste this: /Library/LaunchAgents
• Remove any suspect items. I have no files in my folder.

• Go to Finder > Go > Go to Folder. Paste this: /System/Library/LaunchAgents
• There are a lot of files in here and some are required. Be careful on what you delete. Look for files with the same name as your Notification and another clue is the date of the file. Most will be the same date, any dates after has possibly been added after your OS install. Feel free to ask before deleting to make sure.

• Go to Finder > Go > Go to Folder. Paste this: /System/Library/LaunchDaemons
• Same warning as before. There are a lot of files in here and some are required. Be careful on what you delete. Look for files with the same name as your Notification and another clue is the date of the file. Most will be the same date, any dates after has possibly been added after your OS install. Feel free to ask before deleting to make sure.

• Go to Finder > Go > Go to Folder. Paste this: /System/Library/StartupItems
• Remove any suspect items. I have no files in my folder.

• Go to Finder > Go > Go to Folder. Paste this: /Library/Application Support
• These files won't automatically launch on startup, but may contain files that are used to recreate itself. Look for names associated with the Notifications. Here is a list of what I have in this folder, yours won't match exactly.

Also remove those files in the Login Items section at  > System Settings > General > Login Items.Hopefully for the last time. I have nothing in the Login section and only Adobe Acrobat Reader DC and OSMessageTracer allowed to run in the background.

How are you uninstalling these apps. If you just deleting the apps themselves you've not getting all of the supporting files for the app.

Try using the free AppCleaner 

WARNING: If you use AppCleaner on an app that you have other apps from the same developer, like Adobe, you must be extremely careful checking all checkboxes and deleting.  Some for those files may support other apps from the same developer and deleting them can mess them up.  Adobe apps is a primary example. I know from experience.  For singular apps from a developer it's safe.

For example deleting the 3rd party browser Firefox this is what would get deleted:

Yup, same here…even after macOS Ventura update 13.2.1. Are your Notifications to current apps or just previously deleted apps?

Mine are for currently used apps and no action seems to have an impact. As apps are still used, have not deleted anything in LaunchAgents or LaunchDaemons folders.

Arrgghh!! These daily, repeated notifications are a major PITA!

Has anyone solved this as its driving me mad, this is for a previously uninstalled app
