TROJ_CAGER.A is a memory-resident, non-destructive Trojan that is downloaded from the Internet, dropped by another malware, or manually installed by a user. It appears that this Trojan aims to disrupt browsing activities related to adult or mature materials. It searches the Internet Explorer browser title bar for certain keywords (such as "sex, phallus, or teen.") and when it successfully finds one of these keywords, it will minimize the current Web page and display a message box written partly in Arabic and the rest in English. If the window is left open it continues to display messages in Arabic. Eventually, it displays another message but with the mouse pointer "caged" within the message box area, although the keyboard remains functional. If the user clicks any of the buttons in the displayed messages, they are logged off of their computer.

This Trojan is currently spreading in-the-wild, and infecting computers running on Windows 98, ME, NT, 2000, and XP.
