Windows 10 Pro sporadic hangs during large network file copy

I've been running Norton for years; previous Norton Internet Security and now Norton Security (Premium) and have never had issues.  Within the last couple of months, I noticed that Windows 10 (Pro) sporadically hangs (off and on) while accessing Windows shares on my local network.  I just purchased a brand new machine and loaded up all my software.  Much to my disappointment, the issue exists on this machine as well...

To level set, the behavior I see is as follows...

  • Mouse movement is no longer smooth, jumping between locations versus gliding.
  • Applications (explorer and other) become unresponsive sporadically.  It seems to affect just about everything...
  • The file copy window itself is also impacted, jumping in % versus advancing like normal and unresponsive sporadically.
  • If I cancel the file copy the problem immediately goes away.
  • I chose a test file (8GB mkv) to do some testing with:
    • Copy from local SSD1 to SSD2; no problems
    • Copy from local SSD2 to SSD1; no problems
    • Copy from fileserver to SSD1 via Wired LAN (1Gbps); problem occurs
    • Copy from fileserver to SSD2 via Wired LAN (1Gbps); problem occurs
    • Copy from fileserver to SSD1/2 via Wireless LAN (802.11n); no problems
  • My 2nd machine exacts EXACTLY the same way, down to the LAN vs Wireless LAN differences.
    • Machines are HP Elitebook 8540w and MSI GS63VR-7RF, and are VERY different...

To begin the process of tracking down the issue, I started with Norton Security as it's the only thing I've installed on both machines that's pervasive enough to cause this kind of issue.  Once I uninstalled Norton Security, the problem disappeared.  I can copy files to/from the file server over Wired LAN without issue.  As soon as I reinstall Norton Security, the problem returns...

Is anyone else experiencing a similar issue?  I move a good deal of large files to/from my media server and can confirm this has not always been the case.  I always go from wireless to wired when moving large files so I know it hasn't always been this way.  Looking back, I feel like whatever it is has cropped up within the last few months...

My running theory is that Norton Security can't keep up with the high transfer rates with whatever checks are being done during the network file copy.  If local file copies aren't subject to as much scrutiny, that would explain why SSD to SSD is unaffected.  As far as why Wired is impacted and wireless is not...  My Wired LAN connection is 1Gbps wired from laptop to file server and both machines can definitely push/pull close to the max.  My Wireless LAN connection is limited by my 802.11n access point (Unifi AP).

I know it's a lot to process...  Any ideas?  I'm using Norton Security Premium across 10 devices (Windows/Android) so I have a vested interest in fixing the problem versus replacing Norton!

Thanks in advance!

Re: Windows 10 Pro sporadic hangs during large network file copy

In re-reading my original post, I wanted to clarify one thing.  The issue happens only when copying large files from Windows shares, not all the time...  Sorry for not making that clear above...

Been doing more troubleshooting this morning and it looks like the issue may be related to the Intrusion Detection feature.  If I disable that feature the issue does not manifest during file copy...  I also tried marking my local network as trusted (instead of Private) but that didn't seem to help with IDS turned on...

Hello

I'm sure you have done this, but I will take a chance and ask. Were there any preinstalled security program trials? If so, they have to be thoroughly removed using their removal tool before installing NSP

Since you have just installed NSP in the new computer, there are a lot of background activities which have to get done. That activity might cause issues with your high intensity work. This would be more evident during the Full System antivirus scans.

I schedule my scans for weekly at a time when Computer will be idle and I am sleeping.

Thanks.

Re: Windows 10 Pro sporadic hangs during large network file copy

Both machines began as clean installs of Windows 10 Pro, so the only other security software in question would have been Windows Defender.  As far as new PC tasks, while that could apply to the MSI but the EliteBook had been running for months before the issue manifested.

At this point I have NSP installed and running with the Intrusion Prevention function disabled on the MSI.  I have not seen the issue manifest in this configuration (I moved some pretty large files yesterday in this state).  I rebooted multiple times in this configuration and the machine is running fine.

I'm going to reenable Intrusion Prevention today and see if things come back.  If so, it's a pretty solid case that the IP functionality is the culprit.  Though admittedly I'm guessing that's a case with Norton to report the issue.

Honestly it would make sense that Intrusion Prevention would be involved as it's going to have to inspect all traffic.  The only thing I find interesting is that I don't see it high CPU when this is happening.  I know when I enable Intrusion Detection services on my firewall the CPUs get hammered under heavy loads...

Re: Windows 10 Pro sporadic hangs during large network file copy

I had the same issues on a Win Pro10 (64bit) system with 16Gb ram and SSD, Windows was so slow (not only when transferring large files but even in general use) that the machine became unusable, I struggled for days to find a solutiion and even considered reverting back to Win 7, then I came across your post, disabled 'intrusion prevention' as you suggested and my PC is now running as fast as before, even when IP kicked back in after the 15 minute cancellation period expired.

Hello

I think you can set that to start up on a delayed basis when you boot up.

Thanks.

Re: Windows 10 Pro sporadic hangs during large network file copy

It sounds like the solution may be to use the Norton option to exclude trusted devices on your network from IPS scanning:

If you are sure that a device on your network is safe, you can change the trust level of the device to Full Trust. You can configure the trust level of a device using the Device Trust under Network Settings. You can exclude these trusted devices from Intrusion Prevention scan. Excluding Full Trust devices from the Intrusion Prevention scan saves the scan time and improves the network speed of your computer. When you exclude a device that is set to Full Trust, your Norton product does not scan any information that is received from this device.

Intrusion Prevention exclusion list

When you change the trust level of a device to "Trusted" you should see the option to exclude it from IPS scanning.

Re: Windows 10 Pro sporadic hangs during large network file copy

I noticed that simply turning it back on did not cause the issue to come back, but performing a restart will (in my circumstance)...  Try rebooting and see if the issue comes back.

In my experience...  If I disable it permanently it runs fine immediately and after subsequent reboots...

Re: Windows 10 Pro sporadic hangs during large network file copy

Interesting point on the exclusion list.  I tried marking my network as Full Trust but it didn't seem to make a difference.  I did not try doing it at the device level.  I figured that the exclusion list may not help as it still has to look at the packet to determine whether it should be in scope for scanning or not...

I'll try the device exclusion and see if that helps...  Thanks!

Re: Windows 10 Pro sporadic hangs during large network file copy

It looks like the Intrusion Prevention exclusions are working.  I am currently running Intrusion Prevention enabled with my two main fileservers in the exclusion list with IP scanning disabled for those hosts.  I am not seeing the issue manifest post-reboot at this point.  I'm going to keep an eye on it for a few days but this looks to be giving me what I need at this point.

Thank you for the review/feedback!
