Recycle bin says empty but recycler folder has files

While getting some viruses off my system I noticed this. Norton reported viruses found inside the recycler folder on a specific drive. Theese files have been deleted and removed from the bin so how are they still on my system? I had to go to command prompt to remove the files since explorer will not list the recycler folder.

Strange thing is that in command prompt it will not list anything if you type dir in the recycler folder. You have to know exactly where you are going and type in the long numbered directory name and it will go there and show the files if dir is typed then.

ex. from here (f:\recycler) typing dir will show you nothing
From here (f:\recycler\{big long number} dir will show you the files in it.

Why does it hapen like that? I also wonder what other files are hiding in the recycler folders that I thought where deleted. How can I clean this out?
