  1. Windows Defender has found the following threats on my system.


    First threat: Trojan:Win32/AmsiTamper.A!amsSecond threat: Win32/MaleficAms.CBoth of these threats seem to have affected "powershell.exe"Defender claims they are both "blocked" but they still pop up during every system scan I do. My Defender protection history is filled to the brim with "threat blocked" every minute. How do I purge my system of these threats for good?

    :)

    Windows Defender/Security - no option to "Allow" potential threats?

    If you want to control what does defender do to threats you can do it trough GPO in the following location: Computer configuration\Administrative templates\Windows components\Microsoft defender antivirus\Threats Here configure option: Specify threats upon which default action should not be taken when detected Threats are categorized by level, you assign default action per threat level.
    EDIT: Btw. to open GPO (Local Group Policy) follow these steps: 1. click on start button 2. type: gpedit.msc 3. right click on gpedit.msc and run as Administrator

    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?
