Can't eject creative cloud installer
I have tried all of the solutions I could find on this website, because this seems like a common problem. When I select the creative cloud installer and try to either select eject or just drag it to the trash, I get this message:

I have deleted everything adobe that I can find on my computer, even the acrobat reader, emptied the trash, and still can't get this thing off my desktop. I searched the activity monitor for anything adobe, "code," "cc," "cloud," "daemon" - nothing I do will allow me to eject this thing. It is making me think it is harmful to my computer. Has anyone had this experience and knows what I can do? I'm running my antivirus software now to see if that can help, but nothing so far.
This is my activity monitor, just to demonstrate that there is nothing else adobe that I can quit:
