Windows 10: Windows Security not removing threats, offline scan not working

Today I got a security alert from my Internet provider notifying me of an IP reputation attack. Finding this suspicious, I immediately ran a full scan using Windows Defender and found a handful of exploits and a TrojanDropper have somehow gotten onto my device. Windows Defender tells me every threat on my device is "severe."


I've tried using the "take action" button multiple times. It runs for multiple hours on end without removing the threats. A few times its even given me an error, prompting me to restart the action.


Frustrated with this, I took the forums and found a lot of people suggesting an offline scan with Windows Defender.

I attempted this, but when I do, nothing happens. It warns me that my device will restart, I hit okay. Windows asks for permission to run it, I grant the permission. Nothing.


I've also tried running the Windows Defender Offline scan from the powershell, but I get a permission denied error even though I'm the administrator on my device.


Both my system and Windows Defender are up to date. I do not have any third party antivirus installed on my device, nor have I ever had any third party antivirus installed on my device.


I find this incredibly frustrating and am just wondering if anyone has any suggestions on what my next step should be in removing these threats from my system.

WINDOWS DEFENDER IS NOT REMOVING THREATS

I'm having a problem with Windows Defender the threats found after I ran a full scan that last maybe around 10 hours cannot be removed by windows defender. I selected the remove option and it shows processing but after a while
the threats are still listed and active. I already ran a offline scan and a quick scan but neither fix the problem.

I already ran a secure boot and see if third-party apps are causing the problem but nothing works the threats are still listed and active. I checked the location of the file and manually deleted it even on my recycle bin but
the threats are still there and labeled as active. This very annoying. I think this is an error in the windows defender part because I installed Malwarebytes and ran a full scan which took a couple of hours and found nothing because like I've said I have deleted
the file location where the threats are.

 

WINDOWS DEFENDER IS NOT REMOVING THREATS

Hello PaulPChou,

This one works. You're correct I chose removed but it just doesn't remove the threats it says working and after working the threats are still listed. I ran the safety scanner, reboot, scan in safe mode, scan in clean boot but neither of those works to remove
the listed threats.

Just as I thought all I need is to manually delete the file where it contains the threats list just like a log file.

Thanks for providing the path where it stores the list.

Best regards,

Lelouch

 

Windows Defender Doesnt Remove threats.

Can you give us what is/was the fully qualified name and
path to the file deemed to be a virus/trojan ?

It will be a lot easier to help you remove it once we know what it is and
where its saved into, as it appears under quarantine or on the list of detected items

I suggest you to use Windows Defender Offline in Safe mode and remove the virus and check if the issue is resolved.

Windows Defender Offline is a stand-alone tool that comes preloaded with the latest antimalware updates. It works outside of Windows, which means it can catch and clean infections that hide themselves when Windows is running.

• 
  Go to another PC that isn’t infected and download Windows Defender Offline.
  
• 
  Insert a blank USB flash drive or CD into the PC, and then run the Windows Defender Offline file that you just downloaded.
  
• 
  You will be prompted to install Windows Defender Offline to the blank USB flash drive or CD.
  
• 
  After you’ve installed Windows Defender Offline onto the USB flash drive or CD, insert it into your infected PC and
  restart in
  Safe Mode. You will be prompted to start the Windows Defender Offline tool.
  

The following articles may help if you're having trouble getting the tool to work:

After you've used Windows Defender Offline, you should make sure your security software is up to date and run a full scan:

• 
  Get the latest updates
  

Even if we've already detected and removed this particular threat, running a full scan might find other malware that is hiding on your PC.

Please post to us if the virus issue is resolved. We are glad to help you further.
