Windows 10: How do I purposely get a false positive with windows defender

Let’s say I want to make an exe false positive file by having a file not download or not open without an unnecessary amount of antivirus warnings, and it’s just a png displayed or something, how do I make a file as suspicious as possible.

defender false positive

Hi Bob,

To better assist you, kindly verify the following:

• Where did you submit the file about Windows Defender being false positive?
• Right after the recent Windows 10 update, your Zara Radio stopped working?
• Regarding the 404 error, what application were you using when you got that error?

Let us know.

 

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?

Why does Windows Defender not understand "False Positive"?

Almost daily now, I've had to clear a "threat" from Defender's "actions needed" list on a specific program that is a false positive.

How do I make it work as expected?
