Deleting applications?

As a newbie to this board and my most recent download...after analize; items listed to be deleted were Applications Office 2003 38KB 51 files along with Applications 2007 38KB 51 files. I'm afraid to run cleacner as it states files to be deleted. Will this result in complete hard drive deletion? or are these items I've placed in my Waste Can, or temp files - see i know I've not deleted 51 files lately.

They are only temp files. Not the actual application.

They are temp files, recycle bin and so on.

Just keep ccleaner in default settings until you are more used to it.,
