Downloading CCleaner Full

Keeping your computer clean and tidy is always a good idea. Not only will this help it run its best but also make it more secure (and you in the process). We are very proud of our CCleaner product because it’s the world’s most popular PC cleaner. This isn’t just random luck but the result of a lot of hard work from our developers and ongoing efforts to improve it and add enhancements wherever we can.

We have our famous CCleaner Free version as well as CCleaner Professional (which some people refer to as the CCleaner Full version). We’ll run through the differences later so you can decide which is right for you; for many people, the free version is just what they need.

Why you should download CCleaner from a trusted site

If you download an illegitimate version of CCleaner Pro from a warez or cracking site, or via a torrent or peer-to-peer network, you are putting your computer and data at risk. It will make you more likely to experience:

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

Where to find CCleaner Full safely online

The only place you should download the CCleaner Full (CCleaner Professional) version is via our website or a trusted software hub like the Microsoft store. In fact, this is true for any software: only purchase or download a program or app from official sources. Why? It’s the only reliable way to know you are getting the real deal.

You’re no doubt aware that cybercrime is big business these days and is on the rise each year. It’s constantly in the news and you most probably know someone who has been a victim or even experienced it yourself in some way, shape, or form. Being connected opens up a world of possibilities and is usually helpful but it also leaves you open to hackers if you’re not careful.

Beware of fake/free CCleaner Full versions offered

A very popular scam is to offer software downloads on cracking sites. They’re called this because they offer cracked software: usually paid versions that have been modified and recreated so they can be installed for free. There can be a couple of problems with these sites since their service offering is illegal and therefore unregulated:

Pop-ups or redirects can lead you to dangerous websites or infect your computer The cracked software they offer may have been injected with malware that compromises your data and safety

Of course, not all of these sites have bad intentions but there is no way of telling them apart, and they are all on the wrong side of the law so you have no protection if something does happen.

Cybereason, a security company, estimates that more than 500,000 devices were infected by malware in just one incident (and counting). And if that’s not scary enough, apart from malicious software being used and viruses that steal your personal information, some of these potential threats allow for pictures to be taken using your webcam and pose a complete invasion of privacy.

That brings us to another issue about pirated software and using cracked keys: you won’t get the latest updates. Software is regularly monitored and updated by the developers who created it to make further security enhancements and fix any bugs. This is standard whether it’s an app you download or a web browser that you use. If an important security update goes into a new release, a cracked version won’t pick this up. Or you may miss out on a bug fix meaning the software slows your computer down.
