The article manages to go into almost no detail about the doomsday program, however; it supposedly sends passwords and other information to the hackers, then turns the machine into a zombie for DDOS attacks. Missing are such unimportant little tidbits as how to tell whether or not a computer has the trojan on it. Thanks a lot, guys.
So, in summary, your computer may have a nasty trojan on it that may send critical system data to a hacker somewhere, and make your machine a launching point for a DOS attack. Thanks to a tight-lipped security firm, at this point there's no way to tell if you're one of the lucky winners or not. Sleep well.
