The First Islamic Trojan

It’s true, an Islamic Trojan. Virus writers have created a Trojan horse which tries to disrupt visits the pornographic websites by displaying messages from the Koran.

The low-risk Yusufali-A Trojan horse monitors the websites Windows users are visiting. If the malware sees one of a set of trigger words (such as "teen", "sex" or "penis") in the URL it minimises the window so the user cannot see its content and displays a message from the Koran instead. The message, partly written in Arabic, contains the following English text:

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