I agree. A 'secure shredder' option would be a great function in CCleaner. Windows Washer by Webroot has this feature. Basically, all it does is 'wipe' the files so they cannot be undeleted by way of using random bytes to overwrite the file. Many programs use this, including Spybot S&D. When you just choose to use the basic 'delete' option off your hard drive, the file is not actually deleted. Traces of it remain for long peroids of time, and people concerned about privacy could benefit from this. Especially since one of the main features of CCL is too remove your tracks of where you've visited (MRUs, browser history, cookies, etc). This would just be one more aspect to make the process even better.
