Here is a simple solution : stop relying on the free Windows Defender and buy and use a good anti-virus program.
Problem solved and your pc is better protected.
Anyone active in crypto should not rely solely on Windows Defender for protection.
They should go the extra mile and get some proper anti-virus & malware protection.
Anyways, this thread topic has changed from Windows Defender supposedly detecting a trojan virus to Windows Defender classifying legit software as a PUA (potentially unwanted application). In this specific case it classifies something in the Dash Dash Core wallet ZIP file as a PUA - CoinMiner (which is normal in this case).
I suspect the scanning for PUA's can be disabled from within Microsoft Defender, or the zip file itself can be whitelisted.
It is up to users how they want to deal with PUA's.
And no, a PUA is not a virus.
Here is a doc about it :

Sometimes a file is erroneously blocked by PUA protection, or a feature of a PUA is required to complete a task. In these cases, a file can be added to an exclusion list.
With regards to the found 'trojan:win32/woreflint.a!cl' : most likely unrelated to the Dash Core Wallet ZIP file and an urgent reason to get a good anti-virus program and do a full system scan.

Instead of doing a quickscan you should just have Windows Defender scan the Dash Core wallet ZIP file, if it only finds the PUA CoinMiner, then that means you got the trojan through something else (maybe you downloaded a game or something and it was attached there).
If you are not getting a good anti virus program, at least do a full system scan with Windows Defender & download and use the free Malwarebytes for Windows edition. Make sure it scans for rootkits as well.
