Is ccleaner a trustworthy program

CCleaner has faced scrutiny in the past due to privacy concerns and security issues, particularly after its acquisition by Avast. While it can effectively clean up unnecessary files and optimize system performance, users should exercise caution when granting permissions and ensure they are using the latest version. It's advisable to research and read reviews before relying on it, as there are alternative tools available that may offer similar functionality with a stronger emphasis on privacy. Overall, it can be useful, but users should remain vigilant.
