Todays Defender update triggered an out of date warning.

Yet more weirdness from MS. An hour ago a warning popped up (action centre) reporting Defender was out of date. I haven't missed an update as can be seen. Why Defender itself reports the definitions as created on the 4th Aug I have no idea unless that was the last time they changed from MS. The latest update at the top of the list is from me manually updating just now.

Yeah, same here.

Happen three times to me today. Taskbar Notification on desktop saying virus definitions were out-of-date , then when I viewed the notification, Defender was downloading the definitions itself, instead of them just coming through Windows Update.

No idea why.

Comforting to know its not just me this happened to. All seems back on track this morning, another new definition update installed automatically as normal (I have a task set up to install Defender Updates daily at first boot up)
