Windows 10: Not being Notified by Windows Defender of new Malware Definitions

I don't know why this is, maybe MS has done something on how Defender malware definitions are being notified, but I am not getting them for a few days now. I even re-installed Windows 10 because I had just replaced my HDD with a new SSD drive. Still, no update notifications, except, when done manually. In other words, the updates themselves come through when clicking on Check for Updates, but I am not getting the notifications.

I even have the setting in Group Policy to Notify for Downloads, still nothing for a few days. This is odd, because I used to get Defender update notifications almost every day.

Has MS changed something?

I am running Win10 v1803.

I heard something that MS pulled the feature upgrade v1809 from updating because it had a lot of issues and requesting users to manually check for updates.

Can anyone verify this?

Windows Defender notification of malware detection

Hello,

Thank you for keeping us posted and we appreciate your continued patience on this issue.

At this point, I suggest you to update the Windows Defender program and check if it helps.

To check for new Windows Defender definitions manually:

• Open Windows Defender.
• Click the arrow next to the Help button, and then click Check for updates. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.

Also, check if the detection is of the same malware file or not. Again, see if it is any specific program or a file you try to access which triggers the detection.

Additionally, view the log in Event Viewer to check if the malware is removed every time it is prompted.

To open the Event Viewer. To do so, follow the below steps.

• Go to the Control Panel and choose to click on the
  Administrative Tools icon.
• The above action will open up a new window of the Administrative Tools where you will see the
  Event Viewer.
  

You can view Windows Defender "Operational" events in Event Viewer under Applications and Services Logs -> Microsoft -> Windows -> Windows Defender.

Kindly keep us posted, for us to be able to assist you further.

Thank you.

 

Statistics on the Windows Defender definition list.

Hi, just curious, how large is the Windows Defender definition list?

How many entries of viruses & malwares are there in the definition list?

How many are added to the definition list each day?
