For Windows PC users, you may consider:

PrivaZer

Free. PrivaZer is another great yet free PC cleaner tool that’s packed with utilities to help clean privacy files, remove temporary files and system junks, etc. You may feel a bit overwhelmed by the number of features available on its interface after installing the program on your PC, but it’s actually fairly easy to figure out. Besides regular cleanup, you can also use PrivaZer to overwrite files to your storage device for deep cleaning to ensure data security.

Glary Utilities

Free. It’s an all-in-one utility for cleaning a PC, similar to what CCleaner offers. You can use it to scan and fix Windows registries, as well as clean junk files from web browsers and third-party applications. The program also has a professional version Glary Utilities Pro (paid) which offers several advanced features for power users including enhanced system optimizing and free 24*7 technical support. The latest version is 5.8.5 (Sep. 29, 2017) and is fully compatible with Windows 10.

CleanMyPC

Free to try (500 MB limitation on removing files, and 50 registry fixes), $39.95 to buy for a single license. The program works very well for cleaning unwanted files from your PC. We compared CCleaner with CleanMyPC  and concluded that CleanMyPC is more user-friendly and probably a better option for less advanced users. The latest version is 1.8.8 (2 August 2017) and is compatible with Windows 7, 8 & 10.

Advanced SystemCare

Both Free and PRO versions are available. As the name indicates, it’s a PC system optimization program for cleaning the Windows registry as well as many kinds of junk files. The Free version is free to download and use with limitations, while the PRO version costs $14.77 with an annual subscription.

For Apple Mac users, you may consider:

Onyx

Free. The “Maintenance” module allows you to run miscellaneous tasks like cleaning and system maintenance, e.g. delete apps, run periodic scripts, rebuild databases, and more. The latest version is 3.3.7 and is fully compatible with High Sierra.

CleanMyMac

Free to try (500 MB limitation on removing files), $39.95 to buy for a single license. It’s one of the best Mac cleaning apps in the market, offering a number of utilities for deep cleaning those unnecessary files. The latest version is 3.9 and is High Sierra compatible.

MacClean

Free to try (scan allowed, but removal restricted), $29.95 to buy for a personal license. This is another great cleaning tool for macOS. What’s unique about MacClean is that it has a duplicate finder feature (similar to what Gemini offers), which can help you free up more disk space.

What Else Should I Do?

If you are on a Windows PC, regularly run antivirus and malware scans. For Mac users, it’s always good practice to examine the apps you have installed, as well as make sure the apps you use are up to date. Consider removing unused apps. You can easily do so with CleanMyMac in just a few clicks.

One more tip: Always backup your computer data (or backup of the backups). You never know when another “CCleaner strategy” will hit and what consequences it will cause. If you have a backup at hand, your data is secure, and you can choose to restore your computer if needed.
