So, let's think logically. Nothing else but Windows Defender has found this virus - a virus that is a nasty piece of work and steals your personal data. This kind of virus is top priority for virus companies like Trend Micro, AVG etc. They will have ways and means of detecting it and destroying it properly with their products. Yet you have AVG (according to your hijackthis log) and you have run your pc through Trend Micro. You don't have the registry key that this virus plants, so logic dictates that you don't have the virus.

Windows Defender is still in beta testing - it will bring up false positives more so than something that isn't in beta. Wait for an update and run it again.

Don't worry about it. You will drive yourself nuts. You are very unlikely to have the virus.
