Norton is using too much memory

Hello, Let me begin by saying I am running Windows 10 on 8GB of ram, and have no other applications actively running that I have launched when I encounter the problem and have stopped all unnecessary start-up processes.

Note: I will use past tense in this post because I temporarily solve the problem by disabling the Norton service with the administrative tools.

To the problem now:

Whenever I start my PC it was extremely slow to log into my user, slow to the point where just right-clicking on the taskbar in order to open up the menu to open task manager took 30 seconds, but once task manager was open I checked the memory, and saw that 98% or it was being used up. When I checked what was causing this inordinate amount of memory use Desktop Window Manager was at the top of the list with less than 100MB of memory being used. I made sure that all unnecessary programs were unchecked from startup and rebooted the system. When I was finally able to get back into my account the system was still being slow, and I knew that before installing Norton I was not having this issue, so seeing as there was no startup option I went into the administrative tools and disabled the Norton service, and after rebooting once more, and logging back into my account, I found that the PC was running like butter, I checked task manager and memory usage was down to 20%!

My question is, will I have to keep it like this, because not having an antivirus is no bueno, but I can't even use my computer while norton is a startup process. Do you have any suggestions to try? Have you experienced anything like this?

Thanks.

Re: Norton is using too much memory

Hello egb6869

To start, please turn off Fast Startup as that prevents a proper startup of y our computer. It causes the computer to start up by using the memory to start up. Please see

Here is a link for turning off Fast Startup in Windows 10

http://www.tenforums.com/tutorials/4189-fast-startup-turn-off-windows-10-a.html 

What was your previous security program and how was it removed? What Norton product are you using and what version is it? What operating system are you using? Have you gone thru the settings to set it up as you would like it. In the beginning, there are a bunch of background tasks that need to run while the computer is idle. I would turn down the time it takes to get idle down to 1 minute. That way things will be able to get done more quickly. Please run Live Update to make sure you have all the latest updates and update

The new Norton products are very light on your system for the last few years.. After you upgraded to Win 10, did  you install your Norton product again? Do you have any other security programs installed, even if not running at the time?

Thanks.

Re: Norton is using too much memory

I've seen similar troubles with Win7. I've tracked it to the event where I leave the PC, screen saver time. The status monitor climbs rapidly at the same time Norton is picking up for active scanning. Here are some details:

Win7 Service Pack 1, Dell Precision, Core i7-2860QM, 8GB RAM

Re: Norton is using too much memory

Hello

The 2nd graph is more like when there is a scan running. CPU has to go up a little so that it can get done quicker. In the 1st graph, Norton is using very little. It looks like there is something wrong with either the CPU or with your hard drive perhaps. Is there perhaps some malware? The background activities wouldn't cause so much activity by  the CPU.

Thanks.

Re: Norton is using too much memory

The first chart is memory, the second is CPU, showing the same time segment. The correlation is that once the screen locks due to time out, Norton starts its scanning. CPU use picks up, (no big deal) and memory use also picks up. When I return to the PC, CPU use never falls back to where it was prior to the idle period (measured by Norton as its own usage in yellow), and memory stays 95% saturated. It is never released to near pre-idle time levels. Hours later this is still the same. (Not shown in charts, but observed.) 

By Norton's own measures it is not the heavy user, but it shows that it never completely releases the increased memory it claims to be using. Using task manager, no application is listed as using anywhere near enough memory to reflect the usage of the ~6GB of additional RAM which were ramped up during the idle process, when Norton was starting its idle time scan.

It seems like Norton is the culprit.

If it is malware... why is Norton missing it?

Both possible answers point to Norton stumbling...

If we open my security History this morning to Performance Alerts, the last time High Memory usage was detected was 4/19, and before that on 4/17. From the charts shown above dated 4/24, clearly memory usage was very high... why didn't Norton flag that usage? Today 4/25, the memory usage is still high running over 7GB, but no flags. 

Running a restart resolves the memory usage, until another idle period, and a Norton Scan. The cycle repeats.

Re: Norton is using too much memory

The high memory usage seems to be from other products, rather than Norton.

I'd suggest running a memory check by memtest.   http://www.memtest86.com/

Also try Speccy, which can give you very good info on how things are running on your system.

Re: Norton is using too much memory

I've noticed after a Full System Scan the RAM usage on my machine always remains high, not as high as the screenshot though.  Norton never releases memory for some reason.

Perhaps someone from Symantec could comment ?

Re: Norton is using too much memory

Did you ever get a resolution to this? I was going to re-subscribe to Norton Security but changed my mind after running a full system scan and finding that Norton had caused the RAM use to go up to 98% and the computer to become almost totally unresponsive. I rebooted the PC and then tried a manual scan of a single, albeit large, zip file (Cyberlink PowerDirector 15). Once again, the RAM shot right up and I couldn't cancel the scan. I repeated the test with a smaller zip file (Roboform) and once again it locked up. I'm running Windows 10 64-bit and I've tried other AV programs without any issues like this. Luckily I just managed to cancel my Amazon purchase in time, but I was disappointed that I couldn't use Norton as I prefer it to Kaspersky, which I'm now using.

Re: Norton is using too much memory

No resolution yet. I ran a full diagnostic scan (DELL Boot Level Menu Diagnostics) this morning, NTF (No Trouble Found) with any of the hardware.

Re: Norton is using too much memory

Gents, have any of you managed to get into your Norton dashboard, open "Help" then click "Get Support" to check whether there are patches to be applied? Also as previously mentioned shut down fast startup in Windows as well.

Re: Norton is using too much memory

Update: Uninstalled Norton last night, left it running over night which has always brought out the memory problems. Memory usage stayed low (with Norton uninstalled). Will reinstall and report what the behavior is.

Re: Norton is using too much memory

After a reinstall of Norton the problem is no longer apparent when locking the screen and allowing for idle time. Will update any further behavior changes.

Also, quick start is not activated.

Re: Norton is using too much memory

Update. After leaving the PC running overnight (no applications open) the memory creep is back... Norton seems to have needed some time before displaying its bad memory behavior again.

Re: Norton is using too much memory

As F 4 E pointed out, the screenshots you posted show the high memory usage is by the system, with Norton, shown in yellow at the bottom of the graph, using very little.  Can you check in Task Manager to see exactly which processes are using the most memory?

Re: Norton is using too much memory

The total amount of memory displayed and the memory listed as attached to individual processes are vastly different. The images attached to this post were collected a few moments ago. While there are some big memory allocations in the Processes list, it still does not come close to the 7.47GB used.

In the prior entries, from Norton's usage monitor, Norton didn't release all of the memory it used after an idle time scan, some remained held and reserved by Norton's own accounting. So far, only the action of uninstalling Norton prevents the memory saturation from taking place. When Norton is not installed, other programs use and correspondingly release memory. The ghost memory usage which saturates memory does not occur. And as one would expect, closing any heavy usage application clears its usage. Conversely, when Norton is installed, once the memory has saturated, there is nothing that I can find to close which will end the saturation event other than a restart. Even after a restart, the saturation comes back after a few hours have passed.

Re: Norton is using too much memory

I've been doing "chats"  with Norton help, and the latest recommendation from them is: "I would suggest please post the blog on community again the backend team will check the issue and reply on it."

... waiting ... thank you in advance for addressing this.

Re: Norton is using too much memory

I have this issue on a Win7 device but not Win10. On idle the usage spikes up for no apparent reason. I will do more testing on older platforms and see if I can revive some Laptops and setups to make it work.

Looks like you have a memory leak not in process but from a kernel mode driver. Also it shows your computer has not been turned off / rebooted in about 2 days.

Reboot and set your update speed to low (view->update speed->low) in task manager. Maximize the taskmanager window and take a screenshot after around 45 minutes.

I'd have you use poolmon.exe to show which driver is leaking, but microsoft has made it impossible for me to find you a download link. (they expect you to download a 4 GB iso, install loads of software, just to get a 50KB program)
