used it for years along with malwarebytes
Yes, I also used it for a long time as well. They had some type of security issue with it a few years ago, but that was apparently taken care of when Avast purchased the company. I started using Disk Cleanup, the free tool included with Windows when there were security concerns.
I do appreciate many 3rd party utilities. The free edition that I use the most is MiniTool’s Partition Wizard. I find it more intuitive and more versatile than the built in tools included with Windows. I think CCleaner is similar to that scenario in most ways... it is not something that you really need but it is convenient.

Same here and clean every night before I shut it down. For the small fee, it’s so worth it. Fresh startup when it’s back on!
