Ratingnorton's Common client application, central service that susses out how to operate the main norton stuff which can be tricky in a multi user environment. For example 2 users may be logged on ( say using fast user switching is one way ) And two NAVS are running on two different taskbars, There are Not really two NAVS but just one CCapp controlling the lot... To control the lot independant of user's or before logon you must be a service :) .... Its apparent high CPU usage can therefore be there antivirus or other norton process chugging away doing their job ... allow access for updates etc.  link for more info, another link for more info Jason

RatingWhen we did an uninstall of Norton Internet Security 2003, upon reboot of our laptop, we started receiving and error msg indicating that symstore.dll could not be found. The ccapp.exe was still trying to startup. Jerry
RatingVery Problematic with NAV 2005 & WIN XP. I keep having to uninstall/re-install NAV2005 because on bootup the WIN Install Wizard pops up as though trying to install a program and then NAV2005 auto pops up and says that it does not support the repair feature and I must uninstall/re-install. Susanne Gyasi

RatingccApp.exe is the common hosting application that is used by both NAV and NIS. It calls the different program features in NAV and NIS. For example, in NAV, if Auto-Protect and Email Scanning are enabled, then ccApp.exe makes sure that those programs are running. If ccApp is disabled, then Auto-Protect and Email Scanning will not run.  link for more info oceanMan
RatingI thought I would come back and add the information that Symantec gave me on my problem. In my case none of the below site helped. My problem is CcApp . It is a shame that when you disable their program (Norton) that it doesnot stop this program also from running in the background.  link 1, link 2, link 3 RedOak21
RatingPart of NAV... problem is is that it is now running my CPU at 100% util... and it is stuck there... even after reboots. This happened also once with their Norton Security product.... once again, Symantec crapware strikes again! Ben
RatingIt started to become a problem the day I installed Norton Internet Security 2005 (had not used NIS before). It keeps locking up Outlook, and every time I try to reboot it seems ccApp is hanging and not responding. Simon

RatingThis is a NAV file - However, it does have issues with XP, where it's using from 0% to 98% of my cpu available...Even when not actively doing anything, and NAV is disabled. If I knew the WHY behind this, I could probably work around it, but it's a good case for going to McAfee, less trouble with XP there. Zan

RatingPart of Norton Personal Firewall. You can turn it off by not scanning email.
RatingThis process must always be forced to close on my win xp system, seems like a problematic file.
Ratingseems to be a part of norton antivirus, usually has trouble closing on shutdown, used a lot of memory darcy
RatingAny program can potentially interact with another program. This program does use up some of the CPU but unless you have an old computer it shouldn't be that significant Killafife

RatingI had this problem and it drove me crazy trying to figure what was going on. I eventually determined that if you have the task bar at the bottom of the screen, the ccapp is not a problem. When you drag the task bar to the top of your screen, the problem returns. Strange, but true. Poor programming on someone's part. John B
Ratingit and eventmgr.exe hog up to 85% of my 1.2GHz machine for minutes at a time. Intolerable! Symantec should fix this immediately, or i'm leaving them! [email protected]
RatingCentral to functioning of Norton AntiVirus, Personal Firewall, Internet Security. Takes 44MB RAM under WinXP Pro, but 0% CPU - unless you are constantly running e-mail like Outlook (why don't you exit??) or spending all your time on-line such as with role-playing or streaming media. Better safe than sorry. Stephen
RatingSymantec's bad implementation of ccApp and ccEvtMgr is as big a pain as most problems they want to protect against. Wolfgang
RatingAlso Norton Internet Security 2005
Ratingnorton, i think, because if you shut it down, Norton email security is disabled wagie
RatingIt's an essential application (part of Symantec Norton Internet Security 2004) that works to auto-protect your computer. I agree with previous comments that it slows down your computer and uses a lot of virtual memory. I didn't find this too problematic when running a single program, but multi-tasking can be slow. I tend to disable Norton AV sometimes anyway to speed things up. I never drop my firewall though. Russ
RatingMakes defragmentation by windows disc defragmentor impossible due intermittent disk writing. Is part of Norton antivirus but still active after switching off autoprotect. Can only deactivate using task manager (CTRL+ALT+DEL), Bart Smit
RatingNAV file running in the background - constantly. Eats resources, especially with iTunes running. Mikkel
Ratingit is your autoprotect function. The problems listed are not because of this, they are because people don't know how to set up Norton or Windows. The issue with Norton trying to reinstall and saying it does not support the repair feature is caused by moving the start menu shortcuts or deleting them, not by this app.  link for more info god
RatingNorton's all purpose event handler, very sloppy. Their auto-protect has always sucked, just shut it off and it won't use too much memory. To prevent more memory leak also scan only incoming mail, Norton always has problems when both enabled, no need to scan both direction anyways.  link for more info

RatingccApp is more than a memory hog as discussed at I've install Roxio and ccApp sits at the top of the processes list using up 100% of cpu preventing access to any of my drives using Explorer. Can't put in the background, disable or do anything except uninstall software that is not the cause of the problem. NortonSmith Young

RatingMicroSoft Spyware hotline advised this is a necesary file and should be allowe to connect to Symantec Woodrow
RatingIt belongs with norton.If you have Norton AV it needs to run so it can support Norton. If you like NAV then leave it alone. Its a side pusher to support the emails. If your having problems with it contact Norton. It could be that a virus attached itself to ccApp.exe via back door. If you can Get Spy sweeper and run it to check for any hijackers, ccApp is a vunerable entry because it has no HKEY-Root stabilty. By the way spy sweeper would be a great investment its probably the best out there.  link for more info bluejay

RatingI know it's something for Norton antivirus, but that's about it. It sometimes causes my computer to be slow to shut down though. (I sometimes get the "ending program" dialogue, and that is the process that needs to be ended 90% of the time) Lilly
RatingSymantec accept that this file is necessary and yet do nothing to improve the CPU maxing problems, but go to lengths to say tough if you want the anti virus to run - garbage, I want my subscription fee refunded! Kaz H
RatingIt is a part of Norton Antivirus and Firewall. It renders both of my PCs useless: Windows 2000 and XP home. The XP crashes all the time and the 2000 is so slow and then it crashes. It is a legal app and it is not dangerous. It just renders your computer useless, so useless that if you had a virus you wouldn't know it. Also, ccapp crashes when Antivirus or the Firewall go to so LiveUpdate to get their virus definitions or when any other scheduled program goes out to the Internet (such as Microsoft Updates). Ivana

RatingThis file is extraordinarily annoying. It makes up 98% of my CPU usage, even when not running any e-mail programs. It's very frustrating to disable.
RatingIt stops responding when downloading some messages in OE and Netscape Mail and hangs up the download. Need to restart. Message has to be deleted before it gets to mail prg. Walt
RatingI installed NIS2005 on XP a month ago. Recently the Windows shutdown process became extremely slow (5 minutes or longer). And it always started with closing CCApp.exe. I was very frustrated until I found the following solution: turn off the NIS Personal Firewall and turn on the Windows Firewall instead. Now the shutdown is measured by seconds. Also my internet-enabled programs now can run without a problem. Li

RatingI hate it because it takes much memory and i get error message when i shut down computer Oskars
RatingThis program conflicts with outlook. Think it has something to do with FW not accepting automatic checks for new e-mails when the screensaver is on. The problem has not occured when I'm working on the machine, but suddenly the cabinet fan start up at full speed. All progam are reported as Running, but in the Process window ccApp.exe is showing constant use of 50% of CPU, and use more than 55' kb memory. Can't kill the process, and when I shut down PC, ccApp.exe is not responding. I'll throw in an hour in fixing this. If not solved, NIS will be repaced by Zonelabs ZoneAlarm. bts234

RatingThis program took up approx 96% of my memory... which is pretty inconvenient (keep in mind it happened after running a virus scan or two). I tried to manually end the process in task manager, and it denied me access, so I had to shut down and end it that way. Pretty inconvenient if you ask me.... I wish Norton would fix it. John
