Every process has a file associated with his name, so Windows Defender should detect a file too. If not, this might be an issue with Windows Defender. Please check Windows Defender logs for details.

I just did a little research and found that Malwarebytes should remove your crafty Trojan. You can get a free copy here http://www.malwarebytes.org/mbam.php Download it, install it, update it and do a quick scan first. Follow any removal instructions suggested.
Do a full scan to make sure it's all cleared up. It might take a while so be prepared.
