Well, here is an interesting tale of a virus that seems to have a moral code to impose: a new Trojan named Yusufali-A scans the title bar of the active Web browser window, and if it contains something that leads the Trojan to believe that it's a porno site that is being visited, it displays text from the Koran. No, this is not a wind up. It's true.
When it determines that a pornographic Web site is being shown, the Trojan minimizes that window and displays a message from the Koran instead, Sophos said. If the offending site is not closed, a button labeled "For Exit Click Here" will appear. Moving the mouse to that box will lock it in and the user is forced to log out of Windows, according to Sophos.
Of course, these sorts of things have only limited intelligence, and so one may find one's self locked out from non-porno sites by the Trojan as well. Usually these kinds of things are pro-porn, so it's interesting (and also strangely disturbing) to find one that is not. Our advice? Get your virus software up to date, get that muck off of your machine, and visit whatever sites you want.
