I had the very same problem last week. Just like you I tried all I knew but all went in vain. I Googled for a solution and found a post which asked me to do the following. It worked for me. I hope it works for you too.
- Shut your pc down and restart it on OS 9Check if the files exist. It shouldnít. I know this is a long a not-very-efficient solution. But do we have a go? If anyone else has a better and easier solution even I am awaiting one.
- Follow the path: users/home/desktop
- Drag the files to trash
- Restart with OS x
