SourceCCleaner: Is CCleaner safe?
It is a mainstream product from Gen Digital, though a 2017 supply chain attack distributed malware via an official build. That was resolved, and it remains a fair reason some administrators avoid it.

Yes. 7-Zip operates on Windows, Linux, and macOS. Graphical interfaces are optimised for Windows; Linux and macOS primarily use command-line tools. Port and third-party GUI applications extend functionality on these platforms.
