If the program had been installed in your system exacily, the icon on the desktop is just a shotcut of this program. Please do not remove a program with deleting it using the mouse. In this way, only the icon will be deleted, but not the total program. Please find and uninstall a program from the list of Contrl Panel's add/remove utility. If the Contrl Panel's add/remove utility is unable, try to use Advanced PC Tweaker.
