Windows 10: Windows defender recent threat

Hi guys,


I got a threat in my recent scan with Windows defender.


In my protection history it says threat removed or restored and the only action I have available is "allow".


Does this mean the threat has been dealt with?


Obviously clicking allow doesn't make much sense to me as I'm unaware where the threat came from.


Just the protection history saying threat removed or restored has me a bit concerned.


Any help would be much appreciated.


Thanks!

:)

 

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.
