Windows 10: Windows Defender keeps saying it found threats

The attached picture is usually what I'll find every time I restart/shut down and turn on my Windows 10 PC. It will say it found threats, ranging from Low to Severe, and I keep removing them or 'cleaning them' but they come in 3's every time. I've done deep cleans and scans of my PC but they seem to keep coming. Any ideas? All help is appreciated.

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 keeps saying it finds "potentially harmful software" but nothing listed.

Running latest windows 10.

Defender keeps notifying "potentially harmful software..." but nothing is listed.

Also - when I run a quick scan, defenders says "app detected a potential threat" but nothing is listed in History or in "all detected items".

I don't care about the threat but I do want defender to stop notifying me. I'd like to "allow" whatever it is defender is finding but nothing is ever listed. I would like to fix the problem but I'd be satisfied if I just completely removed defender from
my system to stop the notifications.

What are my options?

 

Threats detected by Windows Defender

If you really want to be sure if those threats are removed completely then I would suggest to clean install Windows. That’s the only way to know for sure.

And always disconnect from the internet next time you encounter malware. That’s the first step to take, especially if you have more than one computer sharing the same network.
