CPU usage high when idle

Is anyone else noticing high cpu usage for NIS 2009 when your computer goes idle?  when i turn the computer on and come back to it later, my vista bubbles screensaver is very slow to respond and then norton shows that the cpu is running very high.  the computer is very unresponsive and the only way to fix this is to reboot.  i've noticed that when i turn the idle scan time to 30min. that it helps, as i can walk away from the computer longer and come back within 30min. and the computer is fine.  so i'm thinking that the problem starts when norton or the computer goes to idle.  i've attached some pics that show the high cpu usage begins at idle.  i have the auto-protect set for early load as well.  any help would be awesome.....  thanks, d

fyi-i'm running pentium 4ht with 2gb ram, vista home premium sp1; tried using norton chat support...they deleted temp files, asked me to do a cleanup and defrag, uninstalled/reinstalled....these haven't worked; in the past i also got the error message "issue 8920, 200" but after uninstall/reinstall this seems to have stopped for now.

Re: CPU usage high when idle

Your issue is not universal, I have practically the same system except that my processor is Core 2 Duo. The logs of your NIS ar in the NortonInstaller folder in Program Files, but I can't locate the thread where there are instructions where and how to send them. So, I guess, just wait for a Symantec employee to come here...

Re: CPU usage high when idle

Hi there,

In NAV/NIS 2009 we have introduced the idle time scheduler. This means that Norton will perform its background tasks (like scanning and getting the latest updates) when your PC is idle. This may explain why you see high Norton CPU usage when you are away from your PC  and the background task is running. Once you come back to your system, your system is not idle anymore, hence the Norton CPU usage related to background tasks should be reduced. Does this explain what happens to your PC?

Can you check your Security History to see what, if any, background task was running?

Thanks

Re: CPU usage high when idle

Hi Dora,

Thanks for writing with some ideas as to what may be happening.  As you described, the Norton CPU usage should be reduced, but I'm not finding that that is the case.  Unfortunately, when I come back to my computer and the computer is no longer idle, the high CPU usage continues. 

Next time this happens I will certainly double check the security history to try to narrow down if this is related to a specific background task.  I'll post my findings when this happens again. 

As a side note, unfortunately I haven't received a response from the email support in over a week.  Should expect a response from them soon?  Or maybe they have dropped my case? 

Thanks,

Dan

Re: CPU usage high when idle

I am having almost the same problem with 1 of 6 laptops I have NIS 2009 installed on.  CPU usage for System goes to 100% and Norton varies between 83 and 97%.  Task manager shows ccSvcHst.exe as the program using these high cpu values. Also the memory usage for ccSvcHst.exe shows 142,302k  ... huge compared to anything else on the system

This does not occur only when the system has been idle.  It occurs during normal use ... typing display slows in Office so that the words appear 2 or 3 behind the typing.  Outlook takes forever to open e-mails.  IE takes a long time to open.  In general the entire system slows to a point it is unusable.

I have uninstalled and reinstalled with the Norton Removal Tool as well as full manual uninstall thru the registry etc and also used  the complete uninstall option doing an add/remove programs uninstall.

Re: CPU usage high when idle

dbrzostowski,

Try turning off "Compressed File Scanning" via the options dialog.  Click on "Settings" (on the main Norton dialog, with the CPU meter), then "Computer Settings", then set "Compressed File Scanning" to "Off".

Let me know if this helps resolve the issue.

Thanks,

Re: CPU usage high when idle

Mike as I noted in my post this situation is occuring without the computer being idle.   Do you think that turning off scan within compressed files is the solution in this case as well.

Kudos0

Re: CPU usage high when idle

hey mike,

turned off the compressed file scan and let my computer run for a while (couple hours) without touching it.  unfortunately the same problem happened.  when i got back to the computer the cpu usage was the same...system-100; norton-99. 

i tried to check the history to figure out what background process, if any, was running around the time it went wrong.  it was unclear since many of them ran in the time when i stepped away and let the computer run.  the ones that did run are... automatic live update, idle quick scan, norton community watch, pulse updates, norton insight scan, norton insight submission. 

after thinking abuot agmns's comment as well.....i remembered that last week this problem occured when burning a dvd.  can't imagine the computer was idle when burning a dvd.  but not sure what requirements need to be met for norton's idle processes to kick in.

Re: CPU usage high when idle

I'm having the same problem.  Soon after my computer goes to idle, it freezes up and the CPU Usage hangs at 100% although the Norton usage (according to it's meter) sits at 0%.  I've checked the Norton security log and it's not really pointing to the problem, and I ran through the problem sequence with Task Manager open (to see if any particular Process spikes when the usage goes to 100%), but none jump out.  Incredibly frustrating! Are there any other system tools/logs beyond these that might indicate what app is being accessed at the time the CPU Usage problem occurs? That would at least point me in some direction.

When I uninstall 2009 NIS, the problem goes away. 

Kudos0

Re: CPU usage high when idle

NIS 2009 is designed to do 90% of its tasks at idle. This is normal. If I sit and watch my pc I am sure I get cpu spikes but I have no need to sit and watch my pc. My screensaver is on by then.

Re: CPU usage high when idle

BrxBy,

The process that I've found that is high when 100% System CPU or High 90%+ Norton is excessive is ccSvcHst.exe

If you want to check much deeper into the processes running when 100%  occurs I would suggest downloading ProcessMonitor and ProcessExplorer from the following Microsoft Systinternals website.  You may want to set your idle time scan down to the lowest wait time so you don't have a huge process list to scroll through with ProcessMonitor.

http://technet.microsoft.com/en-us/sysinternals/bb795533.aspx

This should help you pinpoint what process is running that causes the 100% CPU usage.

Re: CPU usage high when idle

Thanks Mike for solving my problem.  As we found out it was due to SpyBuddy being installed to track some "little people's" chat history.

I've posted my steps below for any other users that may be running SpyBuddy.

Although SpyBuddy is specifically listed in the Exclusions list with NIS2009 I choose to follow the SpyBuddy Help Page at this location http://exploreanywhere.com/exclusions/norton/spybuddy.html and included all exclusions listed as well as Spyware.SpyBuddy.  (Since I did not try it I'm not sure if the Spyware.SpyBuddy exclusion in NIS2009 captures all the files/directories listed on their help page)

Installation of NIS 2009 with SpyBuddy. 

1. If you currently have SpyBuddy installed on your machine UNINSTALL it and save on a USB Drive or other portable device your original installation / setup file for SpyBuddy as well as your License Key.  Eject the USB Device (It can not be plugged in while you install NIS 2009 as Norton may detect the Setup file and delete it)

  • Norton will attempt to remove SpyBuddy as soon as Norton installs that is why you must uninstall Spy Buddy.
  • Norton will detect and remove the SpyBuddy installation file if it is detected on your machine.

2. Install NIS 2009 as you normally would.

3. Run LiveUpdate for NIS 2009 (Double Click on the NIS 2009 icon in your system tray and choose Live Update)

4. Reboot as required at the end of Live Update.

5. Double Click on the NIS 2009 Icon in your system tray.  Choose Settings (top center) and Computer Settings.   In the category "Exclusions / Low Risks" select the configure for Scan Exclusions.  For both the Scan and Autoprotect Exclusions add the following exclusions.

NOTE: The first exclusion assumes that you are installing SpyBuddy to it's default install directory.  If you choose to install it to a different directory that directory must be specified as the first exclusion below.

c:\program files\exploreanywhere\spybuddy

c:\windows\win32sb.dll

c:\windows\sbsysdll.dll

c:\windows\system32\drivers\npf.sys

c:\windows\system32\pthreadvc.dll

c:\windows\sysicept.dll

c:\windows\eacrypt.dll

c:\windows\sb32mon.dll

c:\documents and settings\all users\application data\winsyscfg

Click Apply when you are finished and the OK.

6. Do the same for Signature Exclusions using the list below.

Spyware.ChatBlocker

Spyware.ISpynow

Spyware.Ispy

Spyware.KeyloggerPRO

Spyware.Netobserve

Spyware.SpyBuddy

Click Apply when you are finished and then OK,  Click OK again and close the NIS2009 Screen.

7. Plug the USB device back where you saved your SpyBuddy install/setup file into your computer.

8. Install and Configure SpyBuddy

Re: CPU usage high when idle

Thanks for the advice on how to fix my problem, Mike.

I reinstalled NIS 2009 last night in anticipation of following your advice and pinpointing the problem, but since then the problem has not reoccurred and the CPU usage has been fine.  So I'm crossing my fingers and hoping that the original issue was an anomaly or a glitch in my original installs.

Thanks again.  If it reoccurs I'll reach out to you.

Re: CPU usage high when idle

This is the same exact problem I am having, and it only does it on my desktop pc (my laptop has no issues).  I do not have SpyBuddy installed.  The same process is eating my CPU, 90-99% CPU for ccsvchst (sp?).  The only way I have been able to resolve this is to restart the pc.  I don't know what the fix was they sent to you guys in PMs, but I sure could use it!Message Edited by war02orc on 11-03-2008 10:08 PM

Re: CPU usage high when idle

Looks like you can add me to the 'high cpu usage' club too.  I'm running XP Pro/SP3.  I most recently booted about an hour ago and my ccSvcHost has already clocked upabout 1.2M I/O reads, 140K I/O writes and over 160K page faults.  My system is essentially useless in this state.

Re: CPU usage high when idle

Mine hasn't been acting up for a few days (thankfully), but before that I managed to catch it during the problem with Task Manager opened on the processes.  The CPU spike was being caused by 2-4 processes of "dumprep.exe" running with 20%-35% of CPU usage, with the balance used by ccSvcHst.exe.  As noted, it's been running okay for a few days so I haven't dug any deeper yet.

I've had the MS indexing turned off for years.  It always produced slowdowns at inconvenient times, whether I was using Symantec or McAfee or some other products.  The software works, at least for most of us.

It's called troubleshooting -- it's how you narrow down the cause of the problem and whether it is Norton's or elsewhere, which it often is.

It certainly doesn't compromise your system.

The problem elsewhere.... let's think about that for a second.... I never had a CPU problem until I installed Norton.... so how can it be elsewhere... Unless it's Norton not playing nicely with other apps which then returns us to the original problem, Norton.

I can understand if maybe I installed something afterwards but that wasn't the case...

Let me see someone from Norton take an interest in this issue and then maybe I will be more engaged. In the meantime, I'm not going to solve their problem for them and work through it.... Norton costs real money... it should work out the box without troubleshooting... that's what beta tests are for.

Re: CPU usage high when idle

Although you say you have abandoned Norton -- and since you have 64bit Windows with which I've no experience -- I'll answer one of your questions:

<< I never had a CPU problem until I installed Norton.... so how can it be elsewhere... Unless it's Norton not playing nicely with other apps which then returns us to the original problem, Norton. >>

Situation 1 

When N360 V2 was released I upgraded to it from V1 and immediately when I right mouse clicked on a file in PowerDesk File Manager (which has been around for a long time) to use the Context Menu to select one of the options -- Copy, Properties etc -- PowerDesk crashed.

Didn't happen before I upgraded from N360 V1 to V2 so it must be Norton's fault by your thesis.

But No -- the work around and the fix for this were promptly issued by PowerDesk not by Norton (nor by Microsoft who also got blamed since XP SP3 and VISTA SP1 had just been released and who were swapping blame with Norton too).

And the explanation? Microsoft had started observing certain protocols that they had laid down for Windows much earlier but which even they themselves were not observing. When Norton issued N360 V2 they observed the protocols rather than fudging as Microsoft and others had been doing; PowerDesk did not change to observing the protocol and so ..... PowerDesk issued the fix to cure the problem that by your standards was so obviously a problem with Norton.

Situation 2

Many problems with Windows installations that appear to have no relationship to your monitor are fixed by updating the video driver. That's a fact of life known to troubleshooters.

So life is never as simple as you maintain but I'll leave it with a thought:

Re: CPU usage high when idle

dbrzostowski and others,

If you have this issue, do you use Outlook/Outlook Express to check your email, and do you have Microsoft Outlook Connector installed? This is for checking your Windows Live Mail / Hotmail account using Outlook. After looking at your logs it seems very similar to an issue where Norton has an incompatibility with the Outlook Connector.

Thanks.

For anyone having this exact issue -- you have Outlook and Microsoft Outlook Connector installed, and this causes high cpu usage in NIS 2009 -- we have tracked down the exact problem, and it is something that we can fix. Thanks dbrzostowski and all for helping us narrow it down.

I cannot comment on when the fix will be rolled out, though. In the meantime, I suggest either uninstalling the Outlook Connector, or disabling AntiSpam integration with Outlook to get around this.

Andric,

Can you answer the following questions for some clarification?

1) When you see high CPU usage, can you open Windows' Task Manager and see exactly what process is taking up the highest percentage of CPU?

2) Exactly when do you see this condition happening (e.g. immediately after reboot, some time after, after several hours, etc.)? Do you see this happen while you are using the computer for other tasks (i.e. not idling?)

3) Do you still have Spybot installed, or have you tried uninstalling it -- did this alleviate the problem?

Thanks.

Re: CPU usage high when idle

Hello Andric,

I'm glad to see that your system is running better now.

Just for information, during idle times, Norton will automatically do certain tasks, such as scanning. We do this so we do not interfere with your normal usage of the system. Thus you will see higher than usual CPU/resource activity during the idle time. If you want, you can adjust this through the settings. Click on the "CPU usage" link on top of the System/Norton usage graphs. Here you can change the idle time settings (e.g. time interval).

Kudos0

Re: CPU usage high when idle

I understand the Idle time scan feature & options.  The problem was that it was not shutting down once the computer ceased being idle.
