undeltable folders

rhoos

I inadvertently installed a program that came bundled with a new scanner.
The uninstall was not complete. It left a folder under program files and a
shortcut on the desktop. I cannot delete either of them. All I get is a
popup that says it is calculating remaining time. Nothing happens. There
are no processes from this program running. I have ownership rights. There
are no traces left in the registry. I have tried deleting from a command
prompt. I have tried deleting from safe mode. this is vista ultimate on HP
Pavilion. The undeletable files are apparently not interfering with anything
but it is annoying. Especially having the desktop icon. Have I missed
anything or does anyone have another suggestion?
