The malware in the zip is a trojan downloader largely referred to as Upatre.  This downloader will then probably download it's parter in crime Dyre. Dyre, is Zeus-like banking Trojan, which is trying to capture as much information about your online banking details as possible. It's also being used to then send out the same malware to everyone else by using your own copy of outlook and your bandwidth.
