yes,i know,i disable Norton Protection whenever I install Norton utilities or Systemworks. I'm afraid it's true,mate;- Eraser,nor any other utility for wiping free space/file slack Ive ever tried-including CleanDisk Security,BCwipe,Destroy-It,etc,ALL leave some files,[sometimes dozens of Temporary Internet Files] still there and recoverable in the Free Space! And my hard drive isn't particularly complex,and doesent move sections around as much as many others do.The files aren't just "references" to files,or already-wiped-but still-referred-to-in-the-file-table ones-they're real files,recoverable! trust me,I've been through every possible option there is,with every software program involved directly or indirectly with the issue! you really are best to erase/wipe them out before deletion,and let eraser destroy their file names with that option. hopefully somebody will examine the way Norton WipeInfo works,and either modify Eraser or write a free program that will do the same.
