Windows 10: Recently found a threat from Windows Defender. Paranoid right now.

I have recently downloaded a game from Steam called Pogostuck. At the end of the download, my Windows Defender alerted me a threat. I attached the image of the screen shot. What does this threat mean? It says "Affected items". Does that mean that the file IS the "threat", or does it mean the "threat" affected that specific file. I have ran multiple scans on windows defender and Malwaresbytes because I am currently very paranoid about this. I have also looked at control panels, apps, and browser extensions for anything unusual. Nothing seems to be downloaded without my permission so far. No detections from malware bytes and windows defender at this moment.


I have also reinstalled windows and deleted my drives when I booted up from a flash drive. After doing so, I still got the very same threat message.

Windows defender false positive - forced to allow threat

Windows defender has started to identify C:\Windows\System32\mshta.exe as a threat [normally reported as a Trojan Powessere.G]. I use mshta.exe to run an hta custom MsgBox - I have been hoping to keep using my current CustomMsgBox tool [batch file calling a vbs-hta file] until later this year when I hope to have had enough time to replace it with a PowerShell alternative.

Windows defender's notification lets me "allow the threat" but that seems to me to be a bigger security hole than is necessary - it will now ignore a potentially real intrusion when all I want to run is a genuine Windows component. My immediate problem is fixed but I would prefer to fix the false positive using the exclusions list.

I cleared the 'Allowed threats history' so I could use the exclusions list instead. I added C:\Windows\System32\mshta.exe to the file exclusions list and I checked that it had taken properly by checking the exclusions list both in the UI & in the Registry. But the exclusion made no difference, it continued to detect and block the exe.

I have repeated the attempt several times [by clearing the allowed threats list & exclusions list beforehand] and the results are the same every time
- allowing the threat works,
- using the exclusions list has no effect.

I studied the relevant tutorial but have not spotted an error in what I have been doing - Add or Remove Windows Defender Exclusions

Does anybody with experience of using the exclusions list to counter false positives have any suggestions for me?

Suppress "Windows Defender Antivirus did not find any threats..." notification on Windows 10

You can turn off Enhanced Notifications for Windows Defender:

1. Press Windows + i.
   
2. Click Update & Security.
   
3. From the Update & security sidebar, click Windows Defender.
   
4. Scroll to the Enhanced notifications section and select No.
   

If you do not see Enhanced notifications as an option (likely because you are running Windows 10 15042 or newer), include the following additional steps:

1. Click Open Windows Defender Security Center.
   
2. Click Virus & threat protection.
   
3. Scroll down and click Change notification settings.
   
4. Turn off Receive recent activity and scan results.
   

This will turn of successful updates and only notify you critical events.

 

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.
