Conflict with Norton Security 220.127.116.11 and Windows 10
I had some extra free time this week so I decided, for testing purposes, to install Norton Security 18.104.22.168 on my Windows 10 x64 systems. (Both clean installations, since August 2015, and running all that time without NS).
First of all, my systems do not exhibit the Full System Scan issue reported by many users. I ran 4-5 manual full system scans, all completed without problems, and the duration was similar to previous versions of NS.
However, I have observed the following issue, when NS runs Norton Insight idle task, and the W 10 system is running the Automatic Maintenance, the following error is shown, under Event Viewer and Reliability History.
Steps to reproduce: 1) Let NS idle tasks, and particularly idle Quick Scan and Norton Insight, run at the same time time with Windows 10 Automatic Maintenance which is triggered 4 minutes after the pc is idle. SystemSettings.exe is the executable responsible and running for W 10 Automatic Maintenance. The error, at least on my systems, is logged.
2) Open NS and manually run the Norton Insight task, (by pressing the appropriate arrow, at the same time, open W 10 Control Panel, Security & Maintenance, and click on Start Maintenance. The above error is logged a few minutes after. I uninstalled & reinstalled NS 3 times, when NS is not present, no error, as soon as NS is installed, the problem starts.
If you look at the screenshot, Exception code 0x0000005 indicates a memory access violation so, somehow, NS and SystemSettings.exe do not play fine together.
The workaround, but not a viable solution, because under W 10, Automatic Maintenance is better to run, from time to time, is to apply the following key in the registry in order to disable Automatic Maintenance.
MaintenanceDisabled DWORD 1
Since it appears that Symantec & Microsoft are working closely together for issues like that one, it would be nice if you can take a look to that problem.
P.S. @ all Gurus, please forward this thread to mods, so they can escalate this to the Norton team. Thank you.
