Zeus Trojan (or Zbot Trojan) is a computer virus that attempts to steal confidential information from the compromised computer.
The Trojan itself is primarily distributed through spam campaigns and drive-by downloads, though given its versatility, other vectors may also be utilized. The user may receive an email message purporting to be from organizations such as the FDIC, IRS, MySpace, Facebook, or Microsoft. The message body warns the user of a problem with their financial information, online account, or software and suggests they visit a link provided in the email. The computer is compromised if the user visits the link, if it is not protected.
