Well, it could avoid trashing files or registry entries that perform the KIS update. Generally speaking, the point of ccleaner is to remove things that aren't needed. It's supposed to know enough about the registry keys and files used by various applications so it can avoid breaking them, no matter when it is run. These deletions break KIS. Mike

rridgely, I don't understand what you're asking. Kaspersky looks for updates continuously, and (the way I've configured it) applies the updates silently when it sees them. In this case Kaspersky had received an update, but that update required that the user reboot to complete the update operation. In this case I ran ccleaner after Kaspersky had received the update that required the reboot. I then rebooted, and saw that Kaspersky was then broken. It was healthy before the reboot. Does that answer your question? Mike

I don't have autoclean enabled. I just run ccleaner manually once a week. In this case I ran ccleaner for the weekly cleanup. Kaspersky had automatically updated it's threat signatures. Occasionally completing the installation of new signatures requires a reboot, as in this case. When I saw that a reboot was needed, I did it. After the reboot Kaspersky was broken. Mike

All, I run Kaspersky Internet Security (KIS) (at www.kaspersky.com). This morning I ran ccleaner. I then noticed that KIS said I needed to reboot to install some updates, so I rebooted. After the reboot KIS was broken: several of the components would not start. After some poking around on the Kaspersky forum I found that the problem was that when KIS requests a reboot, it leaves something around to be run when the PC restarts. Ccleaner blows that stuff away, so the KIS update is only partially accomplished, and things go downhill from there. This problem is apparently well known on the kaspersky forum (see http://tinyurl.com/eprdc). After some false starts and with help from the Kaspersky forum, I was able to fix the problem by uninstalling and then reinstalling Kaspersky. It would be great if ccleaner would avoid killing the information that completes the KIS update. I'd rather not have to remember the special cases in which ccleaner does damage. I spent a few hours today killing this problem when I had much better things to do. Thanks, Mike
