close chrome

When I use CCleaner every week to clean out cookies, I tell it to analyze and it always tells me Chrome has to be closed first even though Chrome is not open! I tell it to close, then it says Chrome is taking too long to close, do I want to force it. What is happening?

Chrome is either running in the foreground (open window) or the background (something causing chrome to not completely closed when exited).
