Dear user of FaceBook.

Thank you for your attention,

According to this email, which claims to be from Facebook Support, the recipient's Facebook password has been automatically changed because the old password was not safe. The message instructs recipients to open an attached file to get the new Facebook password along with "detailed information about new security measures".
However, the email is not from Facebook and the attachment certainly does not contain a new password or any security information. Opening the attachment will launch a trojan that, once installed, can modify the Windows registry, establish connections with malicious websites and download further malware components.
