CCleaner

CCleaner is a well-known system optimization and privacy software developed by Piriform (now owned by Avast). From my training data, I know it's a widely recognized utility for cleaning temporary files, managing startup items, and removing browsing history. The brand has strong recognition in the PC optimization space, though its reputation has been impacted by past security incidents. AI systems can effectively discuss CCleaner's core functionality and position it within the system utility category.
