Hi,
I just installed Norton 360 a couple of weeks ago, and since then have experienced very slow performance after the PC has been running for several hours. If I look at my CPU usage, it is up to 100% with the main offender being a program called ccSvchst.exe which apparently is related to Norton (after I searched it on google). Why is this happening and can I solve the issue? This is an older PC running Windows XP, and has 736 MB RAM...a bit slower by todays standards. It seems after a google search, that many people have had this same issue with Norton, especially on older PC's.
I am attaching a screenshot of my Task Manager from yesterday afternoon, where this ccSvcHst.exe is at 95% of CPU. There are also several other SVCHOST.exe programs running. What are all these for? Are they also Norton related?
I called tech support and the lady asked me to run the Norton Cleaner tool, which did absolutely nothing to fix the problem, but wanted to remove some of my bonafide software instead! I'm considering going with a different antivirus software program that doesn't take up all my CPU when it runs....But I'll give Norton another chance if I can solve this issue!
Thanks

Hi,
Well thats good to know this is not wholly related to Norton!
I had Spybot and Windows defender, which were both stopped in MSConfig by the guy that helped me install Norton,(I was having difficulty installing it initially, and called the tech support) so they are not running at the same time. I do however have Malwarebytes, which is running at the same time as Norton, but which the Norton Tech guy said was ok to run together with Norton 360.
The tech guy also went through my start up list and stopped several things that didn't need to run on start up. I'm wondering if what he did might have messed things up? He took control of my PC at the time, so some things he was doing, I didn't really understand. (I'm a bit untechnical when it comes to computers!)
Anyway...I'd love to have an antivirus that runs smoothly, that I can leave on and not have to worry about...
Thanks!
Hi alikirton,
Your system have the capabilities to ran the Norton Product. But, here I would like to give you an information on the file CCSvcHost.exe. It is a common client sharing file, which helps all the processes to run on the datas which is shared by this file. It works for both the Microsoft and the Norton.
And It is not completely because on Norton.
So, my suggestions to you is....
i) Make sure that you dont have all the programs set under the startup menu. Because, these programs will starts work, when windows reboot everytime and that makes your CPU usage high.
ii) Run the Disk Cleanup
iii) Clear all the temporary files and the temp folder
Let me know, how your system reacts...
I see that you are running the real-time version of Malwarebytes. While the technician was correct that it is comptible with Norton, that is regarding the free version, the one that only runs as an on-demand scanner. The one you are using is running in real-time, and this might indeed cause conflicts with Norton. I'd suggest you uninstall it or disable the real-time scanning function and see it that helps. Two real-time anti-malware scanners at the same time is a recipe for trouble. Malwarebytes is fine to have installed and run an occasional scan, but not running in real-time at the same time as Norton.
Hi alikirton,
Malwarebytes' could be an issue. There is a free version which is an on-demand scanner, which does not interfere with Norton. But there is also a paid version which runs in real time and will create a conflict. Your Task Manager shows Malwarebytes' processes running, so that would indicate that it is running in real time. You should disable, or even uninstall Malwarebytes'. The earlier advice you recieved to keep Malwarebytes' was probably based on a misunderstanding about which version you had installed.
Hi,
Ok, I have disabled Malwarebytes. (I don't want to remove it completely, as I paid for it! - it might come in handy as a scanner someday).
My CPU usage is looking better. Computer is a bit faster now...Here is a screenshot of the latest Task Manager Processes window. Could anyone tell me if the number in the CPU column is the % its using of the avaiable memory? If so, why is my System Idle Process now at 97? I don't think I'm really understanding that properly...
Thanks for the advice - I think disabling Malwarebytes has solved the immediate issue!
The entry in the CPU column is not memory, but CPU usage, how much of the CPU processing power is used by a certain program or process.
The System Idle Process is the Windows equivalent of your computer rolling its thumbs. A CPU can't just do nothing, so when nothing else is going on, the System Idle Process runs. The higher the System Idle Process, the lower the activity on your computer. So that's just fine; when nothing is happening, the System Idle Process should be as high as possible.
Glad to hear that the issue seems fixed. What was happening was probably that Norton scanned and monitored everything that Malwarebytes was scanning, which caused the high CPU usage.
Thanks everyone who responded!!
Glad I got this resolved so quick...Norton now has one more continued customer!
Hi AGAIN -
This issue is STILL not resolved...after the PC was on all day today, I went to work on it and lo and behold, CPU usage was up to 100% again and just staying there. Everything came to a standstill.
Malwarebytes has been disabled, so that is no longer in confliction. After I reboot the computer, CPU usage is back to normal. Here is the screen shot of the Task Manager at the time: If anyone knows what could still be conflicting with Norton 360 - please help!!!
I have a defragger (seen on screenshot as dkService.exe) but I have it set to NOT run in the background, but only run on demand. I disabled that from opening on startup, just to see if its a problem. I would like to have that at least be able to open when I do need to run a defrag..if I disable it in MS config, it will not launch the program at all.
Is there anything else running here that is conflicting with Norton to make my CPU usage so high? What is dumprep.exe???
Thanks
Dumprep.exe is a Microsoft application that runs and write an entry into the log when a serious error has occured on the system:

Unfortunately, I see nothing in your task manager image that could be interering with Norton. But dumpreps point to something being wrong, but if it's related to Norton in any way, I can't say. Maybe if I was sitting in front of your computer, but it is much harder to diagose something on a forum.
