UserAgent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_13_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.77 Safari/537.36

Steps to reproduce the problem:
1. Looked for chromium to delete in privacy settings using computer firewall access
2. Removed chromium
3. Tried to put chromium in trash but wouldn't go

What is the expected behavior?
I want to delete this app and not deal with it as a private user.

What went wrong?
The popup says Do you want the application chromium.app to accept incoming connections.  This happens multiple times while in my chrome browser.  When I hit deny, nothing happens.  The popups are dsitracting and I want to remove chromium but can't find it listed in applications.

Did this work before? N/A

Please assist me in getting rid of chromium popups on my computer and delete permanently from the computer.
