    Good day all. We would like to wipe our free hard drive space. We have CCleaner. When we go to Options-Settings Normal file deletion (faster) is selected. When we choose secure file deletion (slower) we get the options: Simple (1 pass), advanced (3 passes), complex (5 passes), very complex (7 passes). Which is best to securely get rid of personal data? I know more passes equals longer time. There are predominantly family and school files with some of my wife's small business associated files on the computer.

    Next, it offers an option to wipe the alternate data streams and cluster tips. What are they and is it safe to do?
    Finally, there is an option to wipe the MFT free space. Again, what is that and is it safe to do?

    Thanks for the help.
