Techie Stuff: The Good Torjan

Experts at SophosLabs, Sophos's global network of virus and spam analysis centers, have warned users about a Trojan horse which tries to interrupt surfing of adult websites by displaying messages from the Koran.
"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 viewing of websites it determines are unsavory," said Graham Cluley, senior technology consultant for Sophos. "Of course, it's possible for the Trojan horse to make mistakes and block sites which are not pornographic - such as medical sites, or social sites designed for teenagers."
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") it minimizes the window so the user cannot see its content and displays a message from the Koran instead, which says -

Yusufali: Know, therefore, that there is no god but Allah, and ask forgiveness for thy fault, and for the men and women who believe: for Allah knows how ye move about and how ye dwell in your homes.
