Has something new come along? It’s been so long since I’ve needed to do this that I assume CCleaner has enshittified by now.
Article about it for those interested… According to this it does not still contain malware, but it has been the target of multiple attacks through the years that has in turn compromised many PC’s. The attack mentioned in this article was suspected to be a state sponsored attack by China, not sure about the others.
