Cannot remove Core Sync on Mac OS

Hello,

A few weeks ago I wanted to take a trial for Photoshop and by that, I had to install Creative Cloud. A week later I removed Photoshop and CC altogether from my Mac, however, Core Sync and similar services still show in activity monitor and there's not much I can do about it but close it.

It starts with the computer. How do I remove these things? They do not show up in Applications.
