How do you enable PUP detection engine on Windows Defender?


How do you enable PUP detection engine on Windows Defender? I know that feature only exclusive for Windows 10 Pro, but I heard there's a trick to enable it on the home version as well.

 

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.

 

Overrun by PUP's


Hi, @Skofab:

A bit of clarification...
As the others have pointed out, MBAM Free is only a manual, on-demand scanner that removes PUPs and malware already on the system.
MBAM Premium -- when properly configured -- can help to PREVENT PUPs/malware infection in the first place.

PUPs are not malware, in the strict sense of the term, as explained HERE. But they are generally junk that one likely does not not need or want and they can eventually get one into trouble with real malware.

Having said that, scanning for ROOTKITS and scanning for PUPs/PUMs are actually different settings.
In order to be sure MBAM is properly configured, open the dashboard > settings > detection and protection > non-malware protection and verify that both PUPs and PUMs are set to "treat detections as malware".

If your settings are correct, but the PUPs seem to come back with each scan, then the most likely explanations include:

• MBAM is having trouble removing them for some reason; and/or
• They are re-spawning, either from software/malware on the system, from Google sync or from another source.

If you would like, please follow the steps in THIS TUTORIAL to locate, export and post here as an ATTACHMENT to your next reply an MBAM SCAN LOG from one of the computers. That log may point to an explanation and possible solution.

Thanks,
MM
