When I turn on my laptop I do Health check on CCleaner. It find 40 tracing tools for deleting. When I choose to delete tem, CCleaner will delet it, so there are not any tracing tools in my laptop (at least CCleaner claims it). When I restart my laptop and do Health Check again, there are same 40 tracing tools. It means CCleaner can not delete it. Or can? What should I do? I have been using CCleaner long time and everything was all right. The problem started just a few days ago. What should I do to get rid of it?
