An anonymous reader writes "From The Washington Post's Security Fix blog comes a tale that should make any Windows home user or system admin cringe. It seems the latest version of the Zeus Trojan ships with a command that will tell all infected systems to self-destruct. From the piece: 'Most security experts will tell you that while this so-called "nuclear option" is an available feature in some malware, it is hardly ever used. Disabling infected systems is counterproductive for attackers, who generally focus on hoovering as much personal and financial data as they can from the PCs they control. But try telling that to Roman Hüssy, a 21-year-old Swiss information technology expert, who last month witnessed a collection of more than 100,000 hacked Microsoft Windows systems tearing themselves apart at the command of their cyber criminal overlords.'"
