    Safer Browsing

    Advertisers and websites track your behavior online with cookies that stay on your computer. CCleaner erases your browser search history and cookies so any internet browsing you do stays confidential and your identity remains anonymous.

    Over time your registry can become cluttered with errors and broken settings which lead to crashes. CCleaner’s patented registry cleaner clears out this clutter to make your PC more stable.
