New problem at the same old time: For several days, our TV streaming was interrupted at 9:49 PM by a Norton window suddenly popping up in the center of the screen (see here).
Tonight, the experience was different. Starting at the same time, 9:49 PM, the program we were watching on Amazon Prime Video started getting choppy and ground to a halt in less than half a minute. There was no Norton screen obscuring our view, but on the other hand the screen was frozen: there was no mouse cursor and Windows took minutes to even respond to Ctr-Alt-Del for the Task Manager.
When I finally got back to the desktop, Task Manager was reporting inordinately high memory usage by two Norton processes, NIItoolsSvc.exe and su_worker.exe.I tried to upload screenshots of Task Manager showing memory usage by these processes, but the upload function keeps failing. Suffice it to say that RAM usage was hovering from 87% to 93%, with three-quarters of that taken up by the two Norton processes. (The PC has 16GB of RAM installed.)
We were barely four minutes from the end of the show when this happened. I ended up having to reboot and wait for Windows to settle back down before we could go back to streaming, losing about a half-hour all told including the initial freezing and waiting for Task Manager to show up. But soon after we resumed streaming, the freezing from these two Norton services recurred. We had to resort to a laptop to finish watching literally the last 16 seconds of the program.
This is completely unacceptable performance by Norton 360.
We are currently on Norton 360, version 26.8.11404.0.
