Hi!
I discovered a "bug", example:
1.- You have installed the "Yahoo Toolbar".
2.- You unistall it with the option already available in CCleaner.
3.- You go to de "Cleaner" section and "Applications" tab.
4.- Now you can see the "Yahoo Toolbar" in the list of the applications to be cleaned.
Sorry for my English, I hope you can understand it.
Best regards and congratulations for the application!
