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?

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

 

Persistent Threat Message in Virus & Threat Protection in Windows 10

Hi,

I have recently uninstalled CCleaner from my PC.

Under Current Threats in Virus & Threat Protection, I keep getting the message that there's a threat from Appiriform_CCleaner.

I've tried the option to Remove this but even after a re-boot the message remains.

Can someone please suggest how to resolve this?

Thanks!
