Koran verse replaces porn

A new Trojan horse virus tries to interrupt the surfing of adult websites by displaying messages from the Koran. The Yusufali-A Trojan horse monitors the websites Windows users are visiting by examining the title bar of the active window. If the Trojan finds a word it doesn't like, such as "teen", "xx", "sex" or "penis", it minimises the window so the user cannot see its content and displays a message from the Koran instead. Graham Cluley, senior technology consultant for Sophos, the anti-virus company, said: "Unlike other malware, it appears this Trojan horse isn't trying to steal money or confidential information, but acting as a moral guardian instead - blocking the viewing of websites it determines are unsavoury. "Of course, it's possible for the Trojan horse to make mistakes and block sites that are not pornographic - such as medical sites, or social sites designed for teenagers." The Yusufali-A Trojan horse continues to display messages if the offending website remains open, and after a while it displays a button labelled "For Exit Click Here". As soon as the mouse is moved the box changes to show vertical bars and the text 'OH! NO i'm in the Cage'. The box contains LogOff, ShutDown and Restart buttons and the mouse pointer is locked within the confines of the box. All the buttons actually cause the computer to logout. "This Trojan horse may have been written as a joke, or as a serious attempt to clean-up the habits of internet users," Cluley said. "Whatever the reasons behind its creation, computer users should protect their systems with up-to-date anti-virus software, security patches and a proper firewall." http://www.sophos.com/virusinfo/articles/yusufali.html
