Posted so other folks don't have to spend a bunch of time trying to figure this one out - Moderators, please move at will!
If your ED (well, actually your PC in general) recently started to lose focus (the active screen suddenly started changing) and/or the computer wakes from sleep without visible reason... check to see if your Norton Security recently ran an update. If so, if probably installed a new task in the task scheduler "Symantec Antimalware Protection Mitigation Helper." The software is intended to check if a computer has updated to Windows 10 so it can tell you to update Norton to a version that works with the new OS.
Problem is, it's set to trigger every 30 minutes after login, and steals focus. So you'll be flying along, in the middle of a dogfight, or perhaps just emerging from hyper/witchspace... and suddenly you're not actually in control any more...
The solution is pretty simple (especially if, like me, you don't plan to update to Windows 10 until the bugs are worked out, drivers are updated, and ED is known to work with it): Open task scheduler, look in the library for a folder "Remediation," right click on the "Symantec Antimalware Protection Mitigation Helper" task and select properties, then the "Triggers" tab. Edit the trigger so it begins "At log on" but unselect the "repeat task every X" option.
I wouldn't advise completely deleting the task - it is necessary if you ever update. But certainly only having it run when you boot would be appropriate. Especially as rebooting and logging in is part of the update process...
