In 2017, Piriform was acquired by Avast, a multinational cybersecurity software company. The bundled apps of CCleaner include Google Chrome browser, Google Toolbar and so on. It indicates that the software is bundled with extra bits and pieces like browser add-ons. On the other hand, some users may worry about the safety of CCleaner, as Windows Defender (a built-in antivirus for Windows 10) detects CCleaner as a PUA (potentially unwanted app) recently. On one hand, users need to pay for some advanced features. However, it also comes with disadvantages. Besides, CCleaner 2.27 and later versions can be used to wipe the entire disk or the free space of the hard drive to protect your privacy. It is designed with a variety of features, such as deleting unwanted files left by uninstalled programs, and cleaning browsing history, cookies, log files, system caches, problematic registry keys and other junk files. Now it is available on various platforms, including Windows, macOS and Android. It is developed by Piriform and was first released in September 2003.

Piriform CCleaner is one of the longest-established system cleaners.
