I am currently running NIS 2010. I recently noticed that, for some unknown reason, SLI has been disabled on my 2 nVidia 7900GS. I went into the Nvidia control panel to enable SLI and received a message saying I could not enable SLI until the following programs were closed:
ccSvcHst.exe
I know this executable is related to Norton, but I am unable to end either of the 2 processes that show up in my task manager (says Access Denied when I try to end task). So the big question is, how can I enable SLI if Norton won't let me end the ccSvcHst.exe processes, even temporarily?
I'm really hoping there is a solution to this. Because right now the only solution I can think of is to uninstall NIS and end my Norton subscription.
Does timiman's solution in this thread help you? I found this one post in that thread. Some are blaming the driver and some blame Norton and some blame Nvidia. Thanks.

FYI: I contacted NVidia via two routes about this issue back in July trying to determine the root cause of this problem. Other than receiving transcriptions of my conversations with them I never received any further information. Today I contacted them again and reached a level 2 support escalation person, this time by phone. Although I couldn't get a time frame on this, I feel that they will be researching the issue from their side in the not too distant future and if they determine why they are complaining about ccsvchst and it truly is a ccsvhst issue, they now have my contact information so that we can work toward providing a resolution.
Thank you so much for taking a deeper look into this. I really appreciate your time on it. My own research seems to confirm that ultimately this is an issue with Nvidia. They seem to have singled out ccSvcHst.exe as a running application that must be closed. Doesn't make sense to me, especially when there are over a dozen other processes running at any given time that Nvidia does NOT have a problem with.
Unfortunately, unless they do something about it, my options are still limited to either uninstalling Norton or buying a new graphics card. I won't lie; this is a great excuse to convince my wife I need a new graphics card. ;) But ultimately it would be good to see this issue resolved in the end.
I did get a little more information on this last night. We have our own theories about what might be causing this and it is likely to not be an issue in the 2011 products. If your subscription is current, you can update to the new version for free via the Norton Update Center (make sure that the appropriate language is selected when you go through the process.)
No joy. Upgrade to NIS 2011 but the problem still persists; Nvidia demands that ccSvcHst.exe be closed before enabling SLI. So frustrating.
Is there no way, on the Norton side, to temporarily end or disable the ccSvcHst.exe process? I had hoped I could maybe turn off or disable Norton temporarily, enable the SLI, then re-enable Norton. Everything I've read so far suggests that isn't possible and I certainly haven't found a way to do it aside from totally uninstalling Norton. Any thoughts?

Thanks for the update! Unfortunately, as Flo already pointed out, the two ccsvchst.exe processes are the core of the Norton products and there is no way to disable them. The only work-around for this problem that I've seen so far is to aviod going to the Performance window or restarting after having done so, this action seems to be the culprit for triggering this.
Sorry, Reese, I'm not sure I fully understand what you mean. Which Performance window? And how exactly would I prevent ccSvcHst.exe from triggering? I thought ccSvcHst.exe triggers immediately upon booting of the machine. Sorry for my confusion; you seem to make it sound like there might actually be some way to enable SLI on my machine without fully un-installing Norton. Is that true?

If you read the thread that Flo provided, it appears that the SLI problem does not occur if you never open the main product user interface and, more specifically, access the Performance link on it. Once you do that, you'll need to restart your system, or at least log off and log back on, to allow SLI to be enabled/disabled.
One of us is looking at the wrong thing, I think. Flo's thread makes no mention of any Performance tab or main product interface. The thread discusses different Nvidia drivers and SLI profiles. I can find no mention of accessing any kind of main product interface. Which product? Norton or Nvidia? ccSvcHst.exe activates immediately upon booting the computer. Trying to enable SLI immediately says ccSvcHst.exe must be stopped, which cannot be done.
Sorry for my confusion, but I'm really lost with what you are talking about. Can you post a link of the thread you are talking about?
Did you try the process that timiman used in his 8 steps and read his whole post.? The way he does it, sounds like he has to do it after every reboot though.

My fault, I should have re-read this thread before posting. I'm involved in internal threads on this issue as well and forgot what was said where...
P.S. Still having trouble finding the thread where the performance flip seemed to cause the problem, maybe it was in nVidia's forums... Anyhow here's another nVidia thread that might be interesting.
Yes I had given this a try but had no luck. I never had 6.05 (or any version) of Nvidia System Tools installed though, so I didn't have the exact same configuration that timiman had. I followed his instructions as close as I could though, but Nvidia still wants ccSvcHst.exe closed before allowing SLI to be enabled.
For the record, Nvidia also says that iTuneshelper.exe needs to be closed. That runs even when iTunes is not running, but at least I can kill iTuneshelper.exe in the Task Manager. ccSvcHst.exe cannot be killed though. There is part of me that is a little ticked at Norton for allowing a process to run without giving me the ability to kill it if I want to. This is my PC, dammit! I should have access to EVERY SINGLE PROCESS running, even if that means I might do significant damage. Drives me crazy that a message comes up saying "Access Denied" when I'm trying to do things on my own computer. Really makes me want to uninstall Norton and join forces with a different internet security software company. Bad Norton!

The difference is that if something malicious attacks your PC and is able to turn off ITunes, it does not gain full control of your computer. Because of what they are asked to do, security programs have to be hardened against being shut down by outside agents. If there is a way for the user to kill the process, then malware can leverage that, as well.
Excellent point. Now I'm frustrated that I no longer have a valid reason to be frustrated. Lol. Seriously though, great explanation. Thanks for stepping in and filling me in. Makes total sense, even if it doesn't solve my current problem. How hard would it be for Nvidia to simply NOT look for that process? Sigh.
