    "Great program and the price is even better. I was having problems with my computer loading slowly. I knew it was time to clean it because I've had it for years now. After running this program, my computer now runs smoothly. I tried the Demo but it did not come with all the features so I paid for the full version. I would definitely recommend."

What's the Meaning?

The term "junk files" describes files that remain on a computer after a task has been performed. These are temporary files Windows or other programs created to complete tasks but failed to delete afterward. Junk files can include unnecessary Windows registry entries, log files, broken shortcuts, and downloaded files. These phantom files can pile up through normal use and cause a computer to run below optimal levels.

Did You Know?

We are guessing you are having issues with junk files, which led you to look for the best PC cleaner. Read on before you commit to any tool that promises to get your computer performing at its best. Did you know that a free PC cleaner was caught secretly distributing a malware? In March 2019, researchers discovered a seemingly safe website offering a free PC tune-up tool which turned out to be the AZORult Trojan. This will try to steal your passwords, cryptocurrency wallets, desktop files, and more. Even the most popular antivirus vendors were not able to detect the said software as malicious. So, kudos to you for researching the best cleaner for PC. We hope you take some time learning how to remove malware, too, in case you install a Trojan by accident. Having the know-how to reverse malware damage can be valuable.
