CyberShredder

CyberShredder represents a quick, safe and handy utility that allows you to erase confidential files from your computer permanently. As you know, the normal file deletion will only remove the appearance of the file while the disk still retains the data until it is overwritten.
The actual disk clusters that contained the files data remains intact on your hard disk and can be recovered later. CyberShredder overwrites the space occupied from a file with random data and erases the file, so an unerase utility will never be able to recover it.
CyberShredders simple interface will help you get rid of confidential data permanently. It has three different methods of deleting files including the NSA approved seven-pass file deletion method.
Please note that files and directories erased by CyberShredder can not be recovered using an undelete program. Make sure you use it with care. We recommend that you learn how to use the program by testing its behaviour with some test data first.
