100% Safe Deletion.. one of the biggest problems for Disk/Registry clenaers...

Hi Guys

What do you think about this 100% safe deletion feature? One of the biggest problem with Disk/Registry cleaners is people were scared of cleaning cos they didn’t know if they were deleting something that could cause issue or not.

now you can safely delete stuff, cos you can always go back in time with our System Cleaner…This is a patent pending innovation that no other company is offering… What do you think, pls let us know your feedback…


Good for programs.

But the problem is if you delete something really important (for example a system registry or file) and can’t boot to the desktop to even click the rollback feature, Well… your pretty stuffed ???

I like the idea, but I think it should be used as a last resort and not like this: “let’s delete these entries and see what happens…if it crashes my computer, I’ll just roll back the changes.” I do not think it is 100% safe because of the reasons pointed out by Kyle. Remember the “CSC makes XP SP3 unbootable” problem? (I know it was a bug, but it is an example of the disaster that can be caused by cleaning programs if you are not careful). I believe it is better to prevent people from deleting the potentially harmful entries, and I suggested a design to accomplish this prevention strategy in this post.

The bottom line: it is better to prevent the fire than it is to clean up the ashes and rebuild.
The “go back in time” feature should be the fail-safe if prevention fails (if the fire occurs despite prevention, then the “back in time” feature will be the fire-fighters that salvage the house before it burns to the ground!).

A major part of Comodo’s protection credo is PREVENTION. So it seems to me, that the PREVENTION concept should be thoroughly applied to CSC. CIS prevents others from doing harm to your computer. With CSC, it should be designed to prevent the user from doing harm to his own computer. Again, this suggestion will help strengthen the “prevention strategy” in CSC.


thats exactly the very problem we solved!!!

no matter what you delete during this, you will always be able to boot back into OS :wink: (hence its patent pending)…

its guaranteed to boot back and give you a choice whether to keep the changes or not :slight_smile:


Very nice work then Melih :slight_smile:

Thanks Kyle…

once again, its World’s First System cleaner with 100% safety!!! You can always reboot!!!

This is great news…congratulations on this new technology!

If it is 100% safe, then there is no point in having a category called “unsafe to delete.”
It is illogical to tell the user that something is “unsafe to delete”, but also tell them it is 100% safe.
A solution for the “unsafe to delete” issue still needs to be implemented because something cannot be “unsafe” and “100% safe” at the same time! Somehow, it needs to be re-worked to make the overall concept more consistent.

Possible solutions:

  1. A pop up that says “Deleting these entries may cause your operating system to become unstable. Are you sure you want to delete them? (If your system becomes unstable, you can recover using the ‘back in time’ feature.”
  2. Remove the “unsafe to delete” category altogether.
  3. Change the name from “unsafe to delete” to one of the following:
    “May cause problems if deleted”
    “May cause instability if deleted”
    “Comodo Recovery feature may be necessary if you delete these entries”


I tried the new Beta 1.1.62802.23…and I like the new setting option that lets you turn on/off the search for “unsafe entries” and the fact that it is turned off by default (this is a much better design…good job Comodo!). I still do not like the “unsafe to delete” phrase. I think it would be better to get rid of “unsafe to delete” and to re-phrase the setting option like this:

Show entries for advanced users (WARNING: deleting these entries may cause harm to your computer)

Then, in the reg cleaner results window, list the entries under this heading: “entries for advanced users (WARNING: deleting these entries may cause harm to your computer)”

This makes it explicitly clear that deleting these entries may not be safe, and that you should stay away from this option if you aren’t advanced!
