Is there a way for CCleaner to not only uninstall programs, but also to securely wipe away the deleted programs from the hard disk at the same time? Does software that do this even exist?
Currently There is not a "one-touch" way to do this, but you could run wipefreespace after the uninstall. CCLeaner's Uninstall just calls the normal windows installer, it does not do anything more (or less) than running uninstall from Add/Remove Programs (just known as "Programs" in Windows Vista and 7)
