Windows 10: How do get my computer to stop saying that there may be threats on my device despite...

I recently accidentally downloaded an unsafe .exe file but didn't open it, deleting it from my downloads folder quickly after and removing it from my recycle bin. Even since then Windows security keeps saying there may be threats on my computer. Despite several quick scans, 3 full scans, and a Microsoft Defender offline scan, nothing has been found. Sometimes it does find something but all it shows is the .exe file that I deleted, showing it located in my downloads folder at 11:04 and recycle bin at 11:05 of yesterday.

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.

 

Regions speech not available despite correct language pack install

The issue still remains unresolved, as English (Australia) simply does not show up in the list despite following all suggested steps to date (which I had done previously)
