CC Cleaner ? does it really work?

I have CC Cleaner on my PC (that is what I am using right now), and my Laptop. I have been unable to get an internet connection on my laptop for two weeks. The CC Cleaner gave the laptop a clean-out clear bill of health. But, after a few days , a re-run of CC Cleaner reported numerous problems on my laptop, of internet related useage. How can this be ? The Lap top has not been connected to the internet for two weeks. How do these problems get into my laptop? ISP AOL has some questions to answer too. But they have not responded after questions asked 10 days ago.
