I recently installed a file-sharing program called PPG, short for Pandora Pub Get. It's like a FTP program, which is obviously designed by a Chinese software writer. I decided to uninstall it, but I find that the uninstallation does not remove the right-click option which is "??????(PPG)???". The ??? probably denotes some chinese characters, and the menu option probably means to share the file using PPG. I tried looking through the registry but I can't find the troublesome key. Can anybody help me with it? I have attached a screenshot to illustrate my problem.
