CCleaner has become very popular in helping get rid temporary and junk data in our systems,But did you know that just erasing data, ie., just deleting them or even for the sake ” Shift+Del ” deleting can also be recovered using simple tools.

To do away with such problems CCleaner has 3 Secure types of file deletion methods other than the regular Fast Deleting.

1. 1 Pass Simple Overwrite.
2. DOD (Department Of Defense) 5220.22-M ( 3 Passes )
3. NSA 7 Passes

Passes means the number of times your data is overwritten with random alpha numeric values so that the recovery process gets even tougher.

Open CCleaner — > Click Options to The left and then the Settings Tab

Remember that the Secure File Deletion can get Slower as the number of passes increases.
