burried vista files

I've used CCleaner for 5 years great program, hope anyone that uses it donates. One problem though with the Vista, Cant seam to get rid of any files that are burried in the documents. IE use CCleaner and use the search option for files that I've use in the past and it is still bring up old files that have been deleted. These files are gone but still saved as some type of referance. What gives.

There are 2 other similar threads. Im using Vista Business (32bit) with SP1 and Windows Search v4. I cant reproduce the issue. I've tried several times, but no go. See this thread for more info: http://forum.piriform.com/index.php?showtopic=17331
