I will have to go with what other people have said about CCleaner for the most part, because I only used it 3 or 4 times before CSC came out.
CSC seems to be much more thorough, in that it removes many more registry entries and many more junk files than CCleaner did the few times I used it. But, like several of the posters have stated, it can be somewhat adventuresome to use CSC.
- SAFE DELETION pop-up STILL doesn't always pop up after a reboot.
- SAFE DELETION wouldn't even work right, until this latest version, on one of our Vista computers. After clicking the Finalize or Restore buttons, this computer would always immediately reboot and go into a continuous reboot loop. To stop this, a system restore had to be performed.
- The latest version of CSC has inactivated the NIC Netgear SmartWizard interface and, subsequently, the Internet connection on our other Vista Ultimate computer, but not on the one that previously had the SAFE DELETE problem. I had to uninstall and reinstall the Netgear software to get both the Netgear SmartWizard interface and the Internet connectivity to work again. I have not yet isolated whether CRC or CDC was the culprit. But none of the previous versions of CSC caused this to happen.
- I really like the thoroughness that CSC provides when removing both registry entries and temp files, but the system stability and problems encountered after running CRC and CDC indicates CSC has not reached maturity. It is now a Tweener, somewhere between a child throwing temper tantrums and a head-strong teenager that doesn't always cooperate with its parent (user).
I really love Comodo Internet Security and have found it to be very stable, functional and usable, ever since it first came out in Beta, on our XP and all our Vista computers. Comodo System Cleaner is powerful and has huge potential, but the full public release versions have never been as dependable as CIS was in Beta. Some people have complained about CIS 3.8 needing to stay in Beta longer because of problems that appeared after the final release, but I feel that statement applies to CSC, not to CIS. I realize that CSC is a foray into an area that Comodo was not previously involved in, system cleaning, but the problems that have manifested themselves in the public release versions of CSC indicate that it possibly should still be a Beta product. I like CSC, but I make this comment because I never know what to expect after using CSC.
In regards to the SAFE DELETE function in CDC and the REGISTRY PROTECTION function in CRC, I ultimately don't want to have to use them. I want to be able to run CRC and CDC without encountering any problems after running them. I continue to check these two new functions out to see if they are working like they are supposed to, but I currently have to rely on System Restore when either one of these new functions has a problem. System Restore is currently a more reliable way to correct any problems that have occurred as a result of using CSC, but it doesn't always successfully restore the computer to the chosen restore point. If SAFE DELETE and REGISTRY PROTECTION can mature to the point where they work correctly EVERY time, then they will prove that they deserve to be functions included in CSC, since System Restore doesn't work 100% of the time. I feel certain both these new functions will reach that point.
The few times that I used CCleaner, it never created any unexpected problems for the computer I was using it on. I also use Registry FirstAid, now in version 7.0, and it doesn't create any unexpected probems for the computer that I use it on. It relies on a full registry backup and System Restore if there is ever a problem created by removing registry entries. I ultimately expect CSC to do its cleaning jobs and never create any unexpected problems for the computers that I use it on. I am sure that is the goal of the CSC development team. I feel certain that CSC will get to that point, but it isn't there yet.
