CCleaner has been a mainstay for protecting Windows computers for many years. It was created at a time when Microsoft Windows lacked many built-in protections and features, so CCleaner filled those gaps. Today, those gaps are gone, and many people who install CCleaner could be doing their computer more harm than good.
Hackers have successfully breached CCleaner's security to inject malware into the app and distribute it to millions of users. Security researchers at Cisco Talos discovered that download servers used by Avast (the company that owns CCleaner) were compromised to distribute malware inside CCleaner.
Personal users can download CCleaner 5.34 from Avast's website if they haven't already done so. Previous releases are also still available on the company's website, but the infected version has been removed from the company's servers.
Windows has a built-in Disk Cleanup tool, and it works very well. Microsoft has been improving it, and it works even better in the latest versions of Windows 10. We don't recommend a CCleaner alternative because Windows can already do a great job at freeing up space.
From its name, you can guess that CCleaner is used to clean up your system. In fact, the first 'C' in CCleaner stands for the 'crap' that it can clean out. It has other uses too: Privacy: Delete passwords, Internet files, configuration files, and remove System Restore points from a shared PC.
Yes, CCleaner is absolutely, positively free. The program is 100% freeware, at least as of our latest review. This means that it's free to download and use in its entirety. In other words, the registry scan is free, as is the actual "cleaning" part.
CCleaner is a small, effective utility for computers running Microsoft Windows that cleans out the 'junk' that accumulates over time: temporary files, broken shortcuts, and other problems. CCleaner protects your privacy.
CCleaner (/ˈsiːkliːn?r/, originally Crap Cleaner), developed by Piriform (a company acquired by Avast in 2017), is a utility used to clean potentially unwanted files and invalid Windows Registry entries from a computer.
You could use CCleaner constantly, running it every day with the default settings. However, this would actually slow your computer down in real use. This is because CCleaner is set up to delete your browser's cache files by default.
CCleaner is, in simplest terms, a disk cleanup tool. Its cleaner will delete temporary files, and it also includes tools for uninstalling programs, finding out what files are taking up the most space on your machine, and finding duplicate files. (It's just better than Windows' built-in disk cleanup tool.)

Though the associated account did not initially have domain privileges, the actor was able to obtain them through successful privilege escalation.
CCleaner is perfectly safe to use on SSDs. I only have SSDs in this system and I use CCleaner regularly. The only thing you should not do is defrag but the later versions of Windows won't let you defrag a SSD - even if you tell it to. In fact, that is why Windows Defragmenter is no longer called Windows Defragmenter.
CCleaner, a popular Windows app for system optimization and maintenance, has at some point been hijacked by hackers, potentially tricking millions of people into installing malware on their personal computers. After looking into the problem, they realized that CCleaner version 5.33 came together with dangerous malware.
Should I clean the Windows Registry? The short answer is no - don't attempt to clean the Windows Registry. The Registry is a system file that holds lots of vital information about your PC and how it works. Over time, installing programs, updating software and attaching new peripherals can all add to the Registry.

Re: Avast is a virus itself - DO NOT INSTALL YOU WILL NEVER GET RID OF IT. HE IS RIGHT IT HAS BEEN PROVEN AND INVESTIGATED PEOPLE GOING TO SPEND TIME BEHIND BARS FROM AVAST! SHOCKED don410 you wrote it was a virus in 2018 ages ago. In the news AVG and AVAST are indeed malware.
Avast is not offered during every CCleaner install. Nor will the install option be displayed if Avast is already installed. Therefore, if Avast is installed on your machine, it could be from a previous CCleaner install, where you would have been asked if you wanted to install Avast and were given the option to opt out.
Click the Windows Start button and select Control Panel. Under Programs, click Uninstall a program if you are using the default category view, or click Programs and Features if you are using the large/small icons view. Right-click your version of Avast Antivirus, then select Uninstall from the drop-down menu.
