Everytime I perform a Custom CClean, I am left with the message 'System - Empty Recycle Bin 40,532 KB 68 files', regardless of what type of settings I am running, 1, 3, 7, or 35 overwrites. If I double-click upon this message, I am always shown exactly the same 68 entries, but as there is nothing in the recycle bin that has been emptied several hundred times, wiped, overwritten (set fire to and generally obliviated) I have no idea what these '68 files' refer to - see pictures attached.
