Zeus has been making the rounds on the Web for some time now, and it has gone through a number of revisions and upgrades in recent months. Its creators, who remain unknown, have steadily added more and more features and functionality to the package, including a form grabber for Firefox, the ability to add extra data fields to online banking applications, a backconnect module and support for Windows Vista and Windows 7.
