Windows Defender still running?

[Vincenzo]

I was under the impression that Win Defender is completely disabled when another AV (Norton in this case) is installed. And in fact it will not start when I search and try to run it. But I see in Task Scheduler that the scheduled scan "operation completed successfully" this morning. So is it running the scan or not? I know I can delete the task, just trying to understand if that needs to be done on all the Win 8 computers around here.

Thanks

It might be part of the Windows 8 scheduled maintenance task
