Windows 10: Windows Defender Malware Detection

I get a notice into about half way through a quick scan that preliminary results show malware or unwanted programs may be on your computer. Results will be shown in Details after scan completes. I get this now on every scan I do including full scan. At completion there is nothing in the Details section of the screen. Nothing appears in the History. Is there anyway I can find on what Defender is hitting?

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.

 

Windows Defender Fails Malware Test

Microsoft’s very own antivirus software, Windows Live OneCare, was recently found to be failing Vista users, and now the same has been discovered for its free anti-spyware application. In tests carried out by Australian company Enex Testlab, Windows Defender struggled to detect just half of the malware which it was tested with, with the quick scan finding missing most of the malware and the full scan finding only 53.3%. It would be best to note that the test was financed by competing company PC Tools, which claims the test was unbiased, although the winning software (detecting 88.7% of malware) was PC Tools’ very own Spyware Doctor. Windows Defender was released as a final version in October 2006, so it is relatively new and of course (being free) costs less than Spyware Doctor.

Windows Defender notification of malware detection

Hello,

Thank you for posting your concern in Microsoft Community and welcome to the Windows 10 Family.

From the description provided, I understand that Windows Defender has identified an issue with malware infection.

To be able to assist you better, provide us a few more details on the below questions.

• Is Windows Defender able to remove the threat after it notifies you about the malware detection?
• Do you have any third party antivirus/firewall software installed which works along side Windows Defender?

As an in initial recommendation, I suggest you to run the
Microsoft Scanner to check if it helps to remove the malware infection, in any case if Windows Defender is unable to.

The Microsoft Safety Scanner is a free downloadable security tool that provides on-demand scanning and helps remove viruses, spyware, and other malicious software. It works with your existing antivirus software.
