This is what I would use - Your Uninstaller!
It is a paid software, but it is functional for 15days.
The limitation is, uninstalling only 3 programs at the time, so relaunch the app and again.
It is great tool to remove the stubborn junk!
Remove every part of a program completely. And than install again.
U can use Your Uninstaller! or Revo Uninstaller. The Windows uninstaller will not remove everything.http://www.ursoftware.com/product/uninstaller/ http://www.revouninstaller.com/revo_uninstaller_free_download.html
