Fitsec is a Finnish website based on information security and penetration testing. The reason why I'm doing a review is they have an excellent site, along with a really good download that I found in my feeds from Techworld that mentions a specific download.
The download link is here: http://fitsec.com/blog/index.php/2011/08/15/tool-release-a-banking-trojan-detection-tool/ (a blog post on their site).
This download is free and it checks your computer for "banking Trojans". It can detect the top five banking Trojan families: Zeus, SpyEye, Carberp, Gozi and Patcher. If they are active on the computer it will let you know through your command window. It will also let you know place to find free antivirus software.
Remember the site is in Finnish. The top right corner will give you the option to change the language into English.
