What it can and can't do

CCleaner has many abilities, but it can't do everything. Here's a list of what it can and can't do.

CCleaner can:

  • Protect your Web browsing privacy on a shared or public computer by deleting passwords and other temporary Internet files, so that nobody will be able to see which Web sites you've visited.
  • Protect your privacy for many OS X applications by removing information about files and folders you've accessed using them.
  • Remove traces of documents you've already deleted by securely wiping free disk space.
  • Reduce memory load and speed up boot times by letting you disable unneeded background programs that automatically start with OS X.
  • Uninstall software easily.
  • Manage your cookies - tiny files on your Mac that Web sites use to track your visits.

What CCleaner can't do:

  • CCleaner can't detect or remove spyware or malware.
