Hi jmwang,
I know these Error Reporting Submissions are somewhat confusing. It's kind of like the firewall report stating "you allowed". Additionally, I know you're probably not going to feel comfortable with Norton, considering those reports.
The only alternative would be to either contact Norton Support or conduct a full reinstall of the software (which is what support will recommend).
If you elect to try reinstalling, please review the following Norton Support Document thoroughly.
Next, scroll down to "I need help removing Norton" and click to open and and continue reading. Now download the NRnR tool from that document and save to your desktop.
Next, ensure you are logged in on your PC with an ADMIN Account!
Then double click on the NRnR tool ensuring you set the advanced option to Remove Only. If it asks if you'd like to save any previous setting select No. After your system reboots, Do Not Reinstall!
Once you have Norton removed, I'd like for you do some checks on your system.
First, ensure Windows 10 Fast Start-up is disabled. You can find the instructions on how to turn it off at this Link. Once done, reboot.
Next, run a check disk scan as follows:
To check your hard disk, click on the Windows Start button. In the search box type CMD. Right click on cmd.exe and click on run as administrator. In the command prompt type "chkdsk c: /r" without the quotes. A message will come up asking if you want to check the disk on the next restart. Answer 'Y'. Reboot and the check disk will run before Windows starts up. This will check the file system as well as the physical disk surface. This scan can take a long time, depending on the size of your hard drive. (credit Peterweb)
If check disk comes back good, Reboot yet again.
Next, run the Deployment Image Servicing and Management (DISM) tool (Ref MS Support Doc):
From the Windows Start button, in the search box type CMD. Right click on cmd.exe and click on run as administrator. In the command prompt type "DISM.exe /Online /Cleanup-image /Restorehealth" without the quotes. Then press enter. It may take several minutes for the command operation to be completed. Important: When you run this command, DISM uses Windows Update to provide the files that are required to fix corruptions.
Once DISM has completed and your back at the blinking command prompt, type "sfc /scannow" without the quotes. and then press enter.
The sfc /scannow command will scan all protected system files, and replace any corrupted files.
Note Do not close this Command Prompt window until the verification is 100% complete. The scan results will be shown after this process is finished.
Take a screen shot if any errors/repairs found if any. If no problems were found or it states its repaired them, type "exit" and press enter. reboot again.
Now, log in to your My Norton Account and select to download your Norton Software. Once you've downloaded and reinstall, ensure you run LiveUpdate a couple more times with reboots between until it states no more updates available. Reboot one more time for good luck. 
Keep an eye on things over the next week or so. If you continue seeing error reports related to the software and or have further concerns, I'd recommend contacting Norton Support through this Link
