Need and Usefulness

• While you don't necessarily need an optimizing program to use your computer on a daily basis, CCleaner is useful for protecting your privacy and helping to keep your computer running efficiently. Installing and uninstalling programs and simply using the Internet can allow files to accumulate, consuming valuable hard drive space and bogging your system down to a crawl. Websites can track your Web searching patterns through cookies, which CCleaner removes.
