Blended threats typically consist of three snippets of code: a dropper, loader, and rootkit. As such, many kernel-mode rootkits are developed as device drivers or loadable modules, such as loadable kernel modules in Linux or device drivers in Microsoft Windows. The longer it goes undetected, the harder it is to undo its damage. Even so, I'd like to take a stab at explaining them, so that you'll have a fighting chance if you're confronted with one. http://2theprinter.com/rootkit-virus/rootkit-and-or-virus-ezula-virus.php
