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?
It's normal depending on your computers settings. You can stop some of it happening.
If it's only just started happening for you then have you recently synced your browser?
