From Winferno Software:
PC Confidential allows users to delete their computer history including: Web browser history, the cache, cookies, search history, temporary files, recent documents, Recycle Bin, Windows Explorer history, instant messenger history, chat logs, and media player history. Users can manually scan and delete, run a full-system scan with just one-click, or set the program to scan and delete history each time the browser is shut down. PC Confidential also can shred sensitive files so they cannot be restored. This feature was designed in accordance with the Department of Defense standards (DoD 5220.22-M, the National Industrial Security Program Operating Manual) for data removal, and therefore even state-of-the-art data-recovery tools cannot recover files shredded by PC Confidential. Also, PC Confidential uses security classifications to selectively destroy sensitive private information, while retaining trusted cookies for automatic logins to trusted sites.
