I should start by explaining what Clean Master Pro is, distinguishing it from the mobile versions. Then, discuss the PC version's features—maybe it's not officially released, so I need to check that. If there's no official PC version, the user might be referring to a third-party product or a different software. That's important to clarify to avoid misinformation.

I also need to check if there's any official information about Clean Master Pro 6.5 for PC. Since I don't have access to current databases, I'll rely on general knowledge. Clean Master is associated with Cheetah Mobile. They do have some desktop tools, but not sure about Clean Master Pro. If unsure, it's better to advise the user to check the official website.

I need to make sure the tone is helpful and informative, not endorsing piracy. I should emphasize legal ways to obtain the software. Also, verify if Clean Master officially has a PC version and its release date. If not, mention that and suggest alternatives like CCleaner or other PC optimization tools. Highlight security risks of using unlicensed software, like malware or data theft.
