W32.Navidad is a mass-mailing worm program or virus, discovered in December 2000, designed to spread through email clients such as Microsoft Outlook while masquerading as an electronic Christmas card. Infected computers can be identified by the mysterious blue eye icons which appear in the Windows system tray.
Users who move their mouse cursor over the eyes will be presented with a variety of different messages, including one which states: "Emmanuel-God is with us!May god bless u.And Ash, Lk, and LJ!!"
