I installed the "KnockKnock" program and it detected my Launch items file without downloading.

I can’t remove it because it’s systemic.

I tried all the removal methods but no luck

It's very easy to remove this file.

Just go to your Applications folder in the Finder. Select the "Knock Knock" app and drag it to the trash. Empty the trash.
