"Turn on Virus Protection" Notification appears after the latest update
So after the latest Windows 11 update I constantly get a single notification from Windows Defender claiming that it was turned off and suggesting to "Turn on Virus Protection". Fun fact is that Defender keeps working all the time and never turns off. Another fun fact is that the notification appears at the same exact time, 4m13sec after logging into account (judging by task manager uptime timer). I've heard a similar story from another user experiencing the same issue after latest update, but for him the notification appears at 4m23sec.
I contacted support and they said that they might require multiple feedbacks on this issue from different users to confirm that it's a bug. While my PC was checked by Microsoft support team member and he confirmed that there's no issue with my system. Everything runs perfectly fine and working as it should.
From the side it looks like it's some scheduled event bug, however upon checking task scheduler there was nothing to trigger this notification. As well as event manager shows no visible signs of critical errors on that matter (or at least I don't see any).
It's extremely concerning to me, cause it's the first issue related to Windows Security which happened to me since my first day of using Windows 11. And there's no trace of it, so basically it's unable to identify the source of this bug.
Reinstalling system helped for a while, but after several hours a few minor security updates were installed, and the notification came back. Like i said, it appears only once after each account log in. If my PC goes to sleep, I can wake it up as many times as I want and it won't show it ever again.
Can anyone confirm the same weird behavior after the latest updates? If so, is anyone willing to send a feedback?
This is a known issue reported widely in forums. It might be caused by July Cumulative Update Preview or August Cumulative Updates. We may expect a fix from September Cumulative Updates.

Just started in last few days. I power the computer off when not in use and upon restart I get the exact same message after roughly the same period of time. I tried to return to an earlier restore point, this did not solve anything. Brand new computer not 6 months old. Win 11, current updates, everything was fine 3 days ago.

A few minuets after I log-On I get a notification showing a pop-up asking me to turn on virus protection.
I was having this issue: "Controlled folder access" switched off under "Ransomware protection" So the info in this thread was really helpful in eventually finding (my) real cause. Clicking the pop-up just takes you to the virus and protection instead of the exact toggle that's switched off. Just vague enough to look like a bug to me.
TLDR: Check (every) option under "Virus & Threat protection" because any toggle off will trigger the generic pop-up we're getting. But it's not smart enough to take us to the exact toggle that's switched off.after isuese whit DEFENDER to cant scan update its fixed but back problem notification its just backrool update its dont know fix scann .
I’m also facing a similar issue. After restarting my system, Windows Defender keeps showing a pop-up asking me to turn on virus protection, even though the virus protection is already enabled and working.
Not sure why Defender is showing this warning after every restart. Any idea why this is happening?

Can confirm same issues here since fresh reinstall of Win11 (Insider Preview) on every boot. Reported to MS. Seems they already know but can’t/won’t do anything about it.
same problem here.
Update 15.8
The notification stopped appearing after the restart. Windows Update started working normally again, as well as Windows Defender, which previously wasn’t receiving updates unless I manually clicked to check for them. For some reason, everything has returned to normal now.
