Andrei, no problems here since many version ago, thank you.

I've noticed your progress with CSC, you really do improve the software. My view is still the same though, CCleaner is my choice for every-day-cleaning, and CSC is my choice for every-week-cleaning. What I miss is still all to be described here (still considering #3 to be the most important):
OK, let's be frank.

Pro for CCleaner:
1. Just ONE click to clear everything except registry. The
Power Clean button of CSC is a step in the right direction but it still requires some confirmations during cleaning.
2. Speed. I think CCleaner is faster to make this complete one-click cleaning.
3. Custom paths in CCleaner is very useful. The
Filter Entries in CSC/CDC is nice, but not quite the same as CCleaner's Options | Include (complemented by Exclude).
4. Everything is presented in just one GUI with tab-like style.
5. CCleaner includes privacy cleaning of some applications that CSC lacks. There is however just one example on my system: 7-Zip. Cleaned by CCleaner but not CSC.
These five points are essentially the pros of CCleaner, IMHO. In all other aspects I prefer CSC because I believe it cleans more things, it tweaks the system (Comodo System Settings) and it has SAFE DELETE.
In the end, you can't cover
every file a user want to clean. There are things which are not "reasonable" to add to any cleaning application, thus you need to add it through custom paths.
I can deny myself all the five points above except one: #3! - and that's the reason why I'm keeping CCleaner along with CSC.
You are so close with CSC, and with the brilliance of development you've showed since you introduced CSC in the first place, I'm sure you can take it even higher and make at least one user (me

) forget about CCleaner.
