cannot uninstall or remove the PL-2303 Vista Driver Installer from my list of programs

I've had some extra time and have been cleaning up my Toshiba Windows 7 laptop which has a 32 bit operating system.  I ran across a program in my "Program & Features" list which I cannot remove or uninstall. The program states that it is a (Prolific) "PL-2303 Vista Driver Installer" which is for a USB to Serial bus adapter.  From everything I remember the package that it came in stated that it was compatible with Windows 7 as well, but I could be wrong. That was quite some time ago. In addition, after doing a little research I understand we had some China knock-offs of this product that were around that were or are creating a lot of problems.  I'm not sure which of these could be my problem if either one or perhaps both,...I would just like to get it off my computer.  I did find a removal program/tool for the driver.  I was hoping it might work for the installer, but after doing some reading I found out I was wrong. Any assistance would be greatly appreciated.
