I have El capitan 10.11.4
I found this:
To resolve the issue you need to delete the service which is starting Preferences Panel with NTFS for Mac OS X.
- Go to Applications - Utilities
- Open Terminal
- Type in
sudo rm /System/Library/LaunchAgents/com.paragon.NTFS.notify.plist
- Press Enter and provide Administrator password
- Press Enter again
Preferences pane will not pop up again.
But the file com.paragon.NTFS.notify.plist does not exist.
PS: sorry for my english, im from Argentina
PPS: It does not appear as part of the Login Items
