Fantasy Lock Screen issue

A friend at work installed Fantasy Lock Screen onto her droid. It is a screen lock that uses a puzzle for a combination.

She decided she didn't like it, so she tried to uninstall it. Apparently it is uninstalled, but still some how on her droid. She says it doesn't show in her apps list, but it does show as a widget.

Is there a way to get rid of an app that has already been uninstalled through the app, itself?
