Frequently Asked Questions

Does CCleaner make a computer faster?

This can free up disk space by removing unnecessary files and help reduce startup delays by managing startup applications. However, cleaning temporary files alone does not guarantee a noticeable speed improvement, as results depend on what is slowing down your PC.

Can CCleaner remove viruses or malware?

No. This is a PC cleanup and maintenance utility, not an antivirus program, and it cannot detect or remove malware or spyware. Use dedicated security software to scan for and remove potential threats.

Can CCleaner clean browser cookies without logging you out?

Yes, it includes a Cookies to Keep list that lets you preserve selected website cookies during cleanup. Deleting cookies from other sites may sign you out or remove saved website preferences, so review your cookie settings before cleaning.

Can CCleaner run from a USB drive without installation?

Yes, it can run as a portable application from a USB drive when configured for portable use. This is useful if you prefer to carry the utility between computers without performing a standard installation on each one.

What is the difference between CCleaner and Wise Disk Cleaner?

Both tools remove unnecessary files and browser data, but Wise Disk Cleaner focuses on disk cleanup and includes disk defragmentation and scheduled cleaning. CCleaner offers a broader range of PC maintenance tools, including startup management and application cleanup, making it suitable for users who want more than disk cleaning alone.
