Check out Privazer, the free version does more than enough to clean your PC and protect your privacy on top of that. If you use it, just take some time and study what the options are. Scan first and move your mouse over the options to make sure you mark cookies as safe where you want to stay logged in on.
If you make a donation to get a key then you will have the option to clean your browser after you exit it and schedule cleaning on your PC.
In all honesty Privazer is way better than CCLeaner, with a few exception like it doesn't include the option to clean specific files or folders with the scheduled options.
I used to think CCLeaner was great, but then I heard on these forums that Avast purchased them and included "PHONE HOME" information about anyone using it now. So, when you think about that if it's true then cleaning your PC does you no good if someone is using the cleaning to spy on you in various ways.
Either way, your better off without excess software installed on your PC that you don't use but think you MIGHT use. I've made that mistake myself in the past. Keep it simple and only install what you use, and that means games and other softwares.
Backup what you think you might use later to an external hard drive, and keep only what you actually use on your PC to your main drive. That way you can judge for yourself whatever cleaner you use is doing and see for yourself. Privazer works great IMO. Even the free version.
