CCleaner can delete potentially unwanted files left by certain programs, including Microsoft Edge, Internet Explorer, Firefox, Google Chrome, Opera, Safari, Windows Media Player, eMule, Google Toolbar, Netscape, Microsoft Office, Nero, Adobe Acrobat, McAfee, Adobe Flash Player, Sun Java, WinRAR, WinAce, WinZip and GIMP[9] along with browsing history, cookies, recycle bin, memory dumps, file fragments, log files, system caches, application data, autocomplete form history, and various other data.[10] The program includes a registry cleaner to locate and correct problems in the Windows registry, such as missing references to shared DLLs, unused registration entries for file extensions, and missing references to application paths.[9] CCleaner 2.27 and later can wipe the MFT free space of a drive, or the entire drive.

CCleaner can uninstall programs or modify the list of programs that execute on startup.[11] Since version 2.19, CCleaner can delete Windows System Restore points. CCleaner can also automatically update installed programs and computer drivers.[12][13]

CCleaner also has its own web browser called CCleaner Browser. CCleaner Browser is included to optionally install in the CCleaner installer, but it can also be installed from its website. CCleaner Browser avoids advertising, avoids tracking, has built-in security against all kinds of malware, phishing, malicious downloads, and also avoids unwanted elements such as pop-ups or excessive browser cache. It is based on Google's free and open-source project Chromium. The browser is only available for Microsoft Windows.[citation needed].

                                                                                                          

After Piriform was acquired by Avast, in September 2017, CCleaner 5.33 was compromised by the incorporation into the distributed program of the Floxif trojan horse that could install a backdoor, enabling remote access to 2.27 million[30] machines which had installed CCleaner.[31][32] Avast insisted that the malware was already in CCleaner version 5.33, prior to the purchase of Piriform. Forty of the infected machines received a second-stage payload that appears to have targeted technology companies Samsung, Sony, Asus, Intel, VMWare, O2, Singtel, Gauselmann, Dyn, Chunghwa and Fujitsu.[33][34] On 13 September, Piriform released CCleaner 5.34 and CCleaner Cloud 1.07.3191, without the malicious code.[35]

On 21 October 2019, Avast disclosed a second security breach during which attackers tried again to insert malware inside CCleaner releases. The attempt was unsuccessful.[.
