See my reply in post #6.I've used Ccleaner for many years and have absolutely no complaints or issues with it. Just this year I bought the Pro version more to give Piriform some money for the years of good service than any other reason. I agree with what others have said, the Free version is all you really need. Pro's main "features" are the automatic update and browser cleaning both of which I can live without. I think it does a good job for what I need it for and its relatively light on my system and has NEVER screwed my machines up.
So, to answer your original question, Yes I think Ccleaner is worth it as far as the free version is concerned. You really don't need the Pro unless like me you just want to donate to the developers.
