[Q] How to remove home facebook share button? - GB 2.3.4 topic

I have already removed all facebook related applications that I could find via Titanium Backup, but the share button in the home screen still exists. Does anyone know which apk is responsible for that button or if is there anyway to remove that button from the home screen?
The following is an image showing the share button (which is what I want to remove) on the top of the screen, it appears whenever a user holds an icon for drag&drop action:
