CCleaner was designed from the ground to be safe and secure to use. It has multiple levels of checks in place to ensure that it cannot delete any useful information or documents you may still need. We also certify that it contains no Spyware or Adware.
For the super cautious users we also offer secure file erasing. By overwriting the files before deleting them, making it impossible to recover the data.
