One issue and some suggestions

CCleaner for Windows
1

I have noticed an issue going back many 2.x versions, but i haven't reported it before now.

CCleaner doesn't erase *.lnk files from C:\Documents and Settings\Administrator\Recent, it just deletes them.

I'm using secure file deletion, DOD 5220.22-M (3 Passes).

I'm running THE Administrator account on Win XP Pro SP3, and this issue was also with SP2.

I have verified this by using Recuva.

Would it also possible to add these features to CCleaner:

-Create some automation features which runs the file cleaner, then the registry issues with or without backup, and then closes itself, alternatively shuts down the computer?

-Erase EventViewer Logs?

-If there are any good reverse engineers in the Piriform team, reverse MRU-Blaster and find out what issues it finds, that CCleaner misses.

Thanks.

I also found out now, using Recuva, several *.ZZZ files that actually are *.JPG *.GIF *.PNG files that should have been securely overwritten with DOD 5220.22-M (3 Passes), but they are easily seen in the Preview pane and in the header pane i see PNG, Gif89 and JFIF.

Also find several files that are just renamed to *.ZZZ but in the header i can clearly read different text.

The State column also says Unrecoverable, but these files really are recoverable, only thing done properly is filenames scrambled to ZZZ.ZZZ.

I'm using Internet Explorer 8.

Are files really securely erased with pseudorandom data?

Thanks

Although I don't use secure overwrite every day, or even every week, I've never seen a ZZZ file that hadn't been overwritten.

Can you check that the deleted file's space hasn't been overwritten and you are actually looking at data from the overwriting file? It's also possible that the deleted space has been overwritten and then that file deleted, but you will still see the data. This can happen with edits/copies/defrags/etc.

Why not try a small test. Create a folder, copy in a few jpgs, add the folder to the custom folders to be deleted, right click on Custom Folders in CCleaner and delete. Then run Recuva to see what you can find. Sort by last mod date to get the correct ZZZs.
