Want a CCleaner license key? We know where to find one...

A CCleaner license key is used to protect users from downloading malicious, illegitimate software. When one of our customers purchases a product like CCleaner Professional it comes with a unique CCleaner license key. When they download our software and enter their private key it unlocks the software and they can use it knowing they will get full customer support and updates when they are released.

Why do software companies use a license key? It’s to safeguard their users and their reputation. That’s because cracked software has exploded in recent years. Cracked software is pirated and placed onto illegal cracking sites. Since the software can be handled numerous times before landing there, you never know if it’s been compromised with malware and other nasties. These sites lure unsuspecting users in by promising free versions of otherwise paid software from a reputable source.

We don’t want to see a fake version of our software (or any program) harm any user or their computer. Our tech team works really hard to try and keep people safe through great products such as CCleaner Professional, Kamo, and CCleaner Browser. Many of our programs are free too, and we’ll run through a couple in more detail at the end if you’re interested in speeding up your PC and making it more secure.

Where can I find a CCleaner license key for free?

You’ll find illegitimate versions of our software (and other pirated software) from a warez site or via BitTorrent. They will come with a fake activation key. Sometimes these versions won’t work from the start, sometimes they will but you won’t get all the safety updates because these sites only offer a static version. If you use these to get a fraudulent CCleaner license key (even if you don’t mean to because these sites can look pretty convincing!) your computer and data are at risk.

Here are some of the common issues you could encounter:

  • malware or spyware on your computer
  • a virus
  • a ransomware attack
  • stolen website passwords or account details
  • stolen credit card or bank information
  • personal data or files stolen
  • other digital data stolen, like your web browsing history
  • a keylogger recording what you type so cybercriminals can blackmail you

For these reasons, you should only download software from an authorized site.

Where can I find a CCleaner license key for free?

Now for the good news! You can trial CCleaner Professional for free with no risk and no obligation. There’s no need to enter your personal information or card details, simply download it and you can use it for free for 14 days. After this time, you will move to our CCleaner free product so you still have some protection. In fact, for many of our happy CCleaner users, the free version does just what they need.

We have both options available here so you can easily decide which is right for you. If you like the idea of CCleaner Professional, once you purchase the software you’ll get your very own CCleaner license key.

What other products need a CCleaner license key?

As we mentioned at the beginning, we have a variety of products to speed up and/or make your PC and data more secure. If you’re interested in CCleaner Professional then you may like these programs too:

Kamo - protects your privacy by sending out fake information to trackers, masking your digital fingerprint CCleaner Browser - our secure browser that looks and acts like Chrome except with advanced security features to keep you safe while browsing

You can trial Kamo for free, then if you want to purchase the package for yourself you’ll receive a CCleaner license key (an activation code via email). Our CCleaner Browser is free for everyone and you can start using it in seconds. Make 2022 the year to boost your internet security and privacy online!
