Windows 10 Crashes at Norton Quick Scan after KB4480966 and KB4480979 Updates

I have had four BSODs today and have never had one on this system before (system is about 8 years old). Only changes are that Windows KB4480966 and KB4480979 Updates were installed last night and Norton Live Update completed last night as well. When I check the dump files, every one lists only Norton and the BSOD error is Bad_Pool_Caller.

At first this only happened when i left the computer unattended long enough for norton to perform automatic tasks while the computer was idle. As I began troubleshooting the issue, I asked Norton to perform a quick scan, and about 2 minutes in, BSOD.....So, dump files list Norton running at time of crash, and I was able to recreate the same crash by running quick scan......

In my Norton History, quick scans are performed almost daily, incl. two yesterday, but none today......

Is this a windows issue or norton issue?

System Info:

Clean install Windows 10 Home 64bit  on 500GB SSD (clean install performed May 2018 - Prior system on HDD was the upgrade from Win 8 to 8.1 to 10 - never BSOD)


Windows 10 and Norton updates all current and latest sets. Everything else runs fine until Norton quick scan is initiated.

All other software and drivers kept current and up to date. None of which have updated in the last few days.

At this point I will uninstall the two windows updates and try running a quick scan and see if it still crashes.

Don't know how to uninstall the Norton live updates.

I removed the KB4480979 Security Update for Adobe Flash Player (don't have flash player installed as a program or extension).

Performed a quick scan and scan completed without issue.

Next, I will let system sit idle until Norton performs tasks automatically.

Hello Mike. Could you tell us what the BCC codes are in the dump file? Some small guidance is in MS forums, and annotated here as well. Multiple things can be at fault so I'd like to look at the codes. Especially the faulting module. Also, KB4480966 is for version 1803 on Windows 10. Are you still on 1803? Do you have Windows update set to defer updates to 1809 and/or drivers from Windows updates? Thanks in advance.

Update 2: Automatic Background Tasks completed w/o BSOD. So far uninstalling KB4480966 seems to have resolved the issue.


Thanks for the reply.

Not sure which codes you are looking for. I cannot find any that are specifically labled as BCC or Bug Check Code. The closest are:

As for Win 10 1803 vs 1809:

My update settings are default. My system had not gotten the 1809 before MS pulled the update in October, and until your comment was not aware that they had re-released it for advanced users in mid December. Should I get it, or wait? I do not have Win Update set to defer anything.


Accepted Solution

Final Update/Correction:

I didn't remove KB4480966, only KB4480979 Security Update for Adobe Flash Player. After removing KB4480979, Norton was able to perform all background tasks without causing a BSOD, even after letting the system sit idle for several hours.

Just figured that someone else may have this issue and want to have a solution searchable for them as well.

Hi @RMike Early,  Thanks for reporting in Norton Community Forums. Can you please let us know the Norton Security installed version number?
