Piriform Ltd is a privately owned software company based in London, UK. It develops cleaning and optimisation software for Microsoft Windows and macOS operating systems, plus Android devices.
Piriform tools include CCleaner, Defraggler, Recuva and Speccy. On 22 September 2015, Piriform launched CCleaner Cloud, to maintain computers remotely.
In July 2017, the company was acquired by Avast Software.
In September 2017, researchers discovered that CCleaner was compromised by hackers who inserted a backdoor into the software, enabling remote access of infected machines.
CCleaner has the option to clean computer browser software including Microsoft Edge, Internet Explorer, Google Chrome, and Firefox as well as a computer system's temporary files. It has a separate tab to clean the registry. (A potential backup of regedit is available.) CCleaner's other tools include editing and uninstalling programs, editing the operating system's startup apps and the editing of browser plugins. It can analyse hard disks individually to determine which files are taking the most space. It can search for duplicate files to help reduce drive storage space. It allows one to quickly access system restore points, and it can wipe clean the free space on individual drives to completely remove deleted files.
Piriform's most popular application, CCleaner, has been downloaded over 2 billion times. It is one of the oldest system cleaners, first launched in 2005.
CNET editors gave the application a rating of 5/5 stars, calling it a 'must-have tool'. It was awarded Editor's Choice Award in April 2009 by CNET.
As of January 2014, it has been the most popular software on FileHippo for more than a year, and also has a 5-star editor's rating on Softpedia. CCleaner has been reviewed by Chip.de,TechRadar,PC Magazine,TechRepublic
