Folder left after uninstall of CCleaner.

I uninstalled CCleaner 4.13 on a Win 7 64bit machine and after uninstall CCleaner folder was still in Program Files.

Has anyone else seen this?

Just checking in case it was isolated to the machine that I was uninstalling it from.

Was that machine using something that the install version wouldn't normally have included by default, those two being:

* ccleaner.ini

* winapp2.ini

I think the uninstall may also leave registry data behind if I'm remembering correctly.
