To resolve the "Turn on Virus Protection" notification issue after a Windows update, check that Windows Defender is active in the Virus & threat protection settings and consider submitting feedback to Microsoft if the problem persists, as it may be a known bug. Restarting your PC or logging out and back in may also help temporarily.

Does anyone have a confirmed FIX? I just figured it out.

Confirmed Fix

I just Click the

Windows Security

Then Click the

Virus & Threat Protection

Then Click the

Manage Settings

Then Click

Real-time protection to the OFF position

Wait a few seconds, then

Then Turn it back on

Wait a few seconds, then

Then turn it back off

Wait a few seconds, then

Then turn it back on and reboot the computer; it should be fixed.

I guess you can just turn it off once and back on to fix it. I just did it several times to make sure it fixes it.

Enjoy

I didn't have that happen to me on multiple systems, some with a 3rd party A/V program, others with Defender as the main A/V. I am wondering if this was an interaction with a particular A/V program, that wouldn't surprise me at all. Defender has a very weird relationship with other A/V programs, handing off major duties to a 3rd party A/V program and back again even if the 3rd party A/V is just even is disabled.

I only use Defender personally. I hate A/V programs; all they do is add LAG, and new threats are added after the fact. Basically, like IP banning is just a whack-a-mole. That is why I created the PHP Smartblocker 1.2. It does not care if you are a new threat; if you don't solve the puzzle captcha, you get blocked. This was also coded for human spammers, i.e., click farms, what this means is a human is paid pennies to create an account on your server, giving the spam they post a backlink The way I programmed it stops the click farms because what happens is the human starts the process, and at a certain point the human hands it to the automated process to finish the registration, and when they hand it off to the autoprocess, it changes IP addresses during the process, and then the code forces a new puzzle captcha when the IP changes, and the autoprocess thereafter cannot drag and drop the puzzle pieces and stops it again.

The final coding is a invitation code that is required during registration and if one is not added, they wast their time in the registration form getting 100% of nothing.

Basically, the site is a proven fortress. NO CRAP PERIOD.

Every connection is challenged, and even if we get past that stage, we still need an invitation code and must solve the hCaptcha as well during the registration process.

So the term "fortress" is accurate for my website LOL. I have not had a spam registration in a while.

Anyway I noted what I had to do to stop the A/v popup to enable it when it is already enabled and I saw no solution posted for the issue over at microsoft, So I created this post so others with the same problem after the latest update can simply fix it like I did

Gotcha. Still wondering why that hasn't happened here. Lucky?

Yeah, what Mr Dog says.

Defender, only thing it defends is stopping you from getting access to unlocking software. As for sorting out VIRUSES, MALWARE, SPYWARE, RANSOMWARE, ADWARE and Underwear its pretty much PANTS all round. But you try to download a Workaround shall we say for a program and it immediately wakes up and stops you. BUT it doesnt tell you its done it and trying to trace what its done can be a nightmare to the uninitiated.

Windows Security generally is about like going to Wallmart and paying $2 for something that youd normally pay $300 for the shock horror, its cheap and...

Microsoft asked customers this week to ignore alerts that Defender Antivirus has been turned off after installing the latest Defender updates.

Although this issue has been affecting users in the Release Preview Channel of the Windows Insider program since June, it appears Microsoft didn't notice it until now.

The erroneous alerts appear on affected systems in the Windows Security app and prompt users to "Tap or click to turn on Microsoft Defender Antivirus."

My suggestion worked for a bit, and then it started up again. HEADS UP

The known issue affects all supported Windows client and server versions, including the latest Windows 11 26H1 and Windows Server 2025 releases.

"After installing the latest updates for Microsoft Defender Antivirus, notifications might appear stating that "Microsoft Defender Antivirus is turned off," even though the antivirus is functioning correctly and all settings show it as active," Microsoft explained in a Friday release health dashboard update.

"These notifications can appear when Windows starts and intermittently afterward. They persist even if notification settings are turned off."

Microsoft says it's working on a fix and will release it to affected customers in a future Microsoft Defender Antivirus update.

This isn't the first time Microsoft has told customers to ignore incorrect alerts and errors being displayed on their systems after installing updates.

In April, the company confirmed and fixed a bug that caused invalid 0x80070643 failure errors after installing the April 2025 Windows Recovery Environment (WinRE) updates and addressed an issue that was triggering incorrect BitLocker drive encryption errors on Windows 10 and Windows 11 devices.

In July 2025, it also asked users to disregard erroneous Windows Firewall alerts that appeared after rebooting following the installation of the June 2025 preview update.

One month later, Microsoft said that the July 2025 preview update and subsequent Windows 11 24H2 updates were triggering incorrect CertificateServicesClient (CertEnroll) errors.

I'm guessing this new update fixes this "Virus protection turned off" warning?

Security Intelligence Update for Microsoft Defender Antivirus - KB2267602 (Version 1.457.432.0) - Current Channel (Broad)

This just showed up today. Hmmmm. Did not fix it for me.
