What's posted looks corrupt—it's probably being shown as (/ and not /(, and it's probably under your ~/Library area.

Looks to be software for a Canon scanner...

As for the usual spot for these entries, look in your login items.  > System Preferences > Users & Groups > Login Items > click the padlock and authenticate...

Apple hid the Users' Library folders...

Method 1:

1 From the Finder, select the Go menu at top of the screen, and choose Go to Folder.

2 In the window that opens, enter ~/Library, and click Go.

Method 2:

1 Go to the Finder (or desktop).

2 Hold the Option key on your keyboard, and click the Go menu at the top of the screen.

3 With the Go menu open, you'll notice that pressing and releasing Option will display or hide the Library choice in this menu.

4 Select Library from the Go menu (while holding down Option) to access the hidden folder.

Method 3:

1 Click anywhere on the desktop so Finder is the name of the foreground app shown at the upper left.

2 Press Command+Shift+H

3 With your home folder open, press Command+J. This the only place you'll see a check box to Show Library Folder. Turn it on.

4 From now on, your user account Library folder will be visible without having to use special keys or commands to get there.

Method 4: Press ⇧⌘. —the command-shift-period chord—to toggle the display of the hidden files, and the Library folder will then become visible in your home directory. And will become invisible, when you press that chord again.

Thanks . :)

If it’s an entry listed in Users & Groups, remove it there and see if the message foes away.

Great to hear. :)
