Security :: Windows Defender Giving Errors And Warnings Constantly

I downloaded a custom keylogger made in Visual Basic. (To tinker with the code and see how it works, nothing malicious.) but suddenly Windows Defender gives me an alert.

I'm thinking it's just a harmless little mistake, so i deleted the files and cleaned my PC with MalwayreBytes, Spybot & Windows Defender.

MalwareBytes found 8 virus'.

Spybot found 5 virus'.

Windows Defender found 7 virus'.

I removed them all and it seemed fine now, but i was wrong.

Windows Defender keeps popping messages up saying that there is a new virus found:

1. The icon that shows when something is removed but the virus ISN'T removed.
2. It gives me an error in the "Status" bar and it doesn't have the "Removed" text in the "Anbefalet Handling" as it normally would have but rather "Quarantine".
3. Immediately when it has "cleaned" my PC, this message pops up telling me there's a virus found and i need to scan it again to remove it.

It's the same virus: HackTool:Win32/Passview

The weird thing is, i recovered my PC to an earlier stage, where i haven't downloaded it and it's still detecting. It's like nothing happened at all. I think Windows 8.1 kept my files, just not the programs i had installed.

When i click on "View all elements found", another 3 virus' are found:

They're all in "Quarantine" and not "Removed" as they should be.

This is the log that Windows Defender produces:
