7 Best CCleaner Alternatives you can Trust to Remove Unwanted Files



CCleaner is one of the world’s most popular software for removing junk files on personal computers and Android phones. This free software tool optimizes device performance by purging unwanted files. It also protects the user’s privacy by deleting private data (for eg, browser cookies etc.,). Recently, Piriform (acquired by Avast), the company that develops this tool announced in a blog post that it had suffered a serious malware attack. The attack resulted in the infection of an estimated 2.27 million users’ devices. This has left users seeking for other alternatives to CCleaner. Before we dive into some of the best CCleaner alternatives available to us, let us understand what CCleaner is, should it be used at all, and how serious the malware attack was.

The Best Alternatives to CCleaner

What is CCleaner?

CCleaner is a utility program that helps in getting rid of potentially unwanted files and invalid windows registry entries from a computer. The first use case this definition brings to mind is freeing up memory from the hard disk. This is hardly a concern nowadays, given that hard disks come cheaper with greater storage capabilities. As such, CCleaner can assist in getting rid of cache files and browser cookies which store private data. Since anyone with access to these files gains immense information about the user, deleting these files is the easiest way to prevent this. Also, CCleaner cleans up files that have been created by background processes (like cookies and cache) which users do not manually delete. CCleaner also provides a startup manager, an uninstaller, and a System restore interface. Since these tools are already built into Windows, most users don’t exploit these functionalities anyway.

Should you be using CCleaner?

Most of the functionalities CCleaner offers is already built into the Windows operating system, and as such do not require additional software to accomplish. And since every computer comes with much bigger hard disks than they did before anyway, the disk cleanup feature might not prove much useful too. Unless your hard disk is running full, using CCleaner might not provide a huge boost in performance. The software does delete temporary files, but deleting some of these files (like the web browser’s cookies and cache files) might actually slow down the computer.

Coming to the registry cleaner, this feature is best left unused unless bad registry entries have left your system damaged and programs refuse to launch or install. The windows registry is a database containing settings for virtually everything on your PC, so messing up the registry might have serious consequences. Unless you are an advanced user, using the registry cleaner is not advisable.


Using CCleaner is not necessarily a bad idea, but most of its functionalities are redundant, given they are already built into the Windows operating system. If you are unsure of some of the options, especially the ones pertaining to the registry settings, it’s best left untouched.

Malware Attack

On September 12th, 2017, Piriform revealed in a blog post that CCleaner version 5.33.6162 and CCleaner Cloud version 1.07.3191 had been compromised. These versions of the software had been modified illegally before it was released to the public. The malware in question was collecting data such as the computer name, IP address, list of installed software, list of active software and list of network adapters from infected machines and transmitting this information to an unknown third party server in USA. Piriform worked with law enforcement officials to shut down the server and claimed that over 2.27 million users were affected. Of these 2.27 million users, 40 received a second-stage payload. Most of which seems to have been targeting technology giants like Samsung, Intel, and VMware.

Piriform urged all CCleaner users to update to the new version, while themselves automatically updating all users of CCleaner Cloud. It appears that users with 32 bit Windows machines were specifically affected. None of the Android devices running the software were compromised. The company is moving the product build to a more secure and robust infrastructure to prevent any such future security incidents.
