The real fun part in all of this is that the virus contacts a web site in Japan to obtain instructions on how to affect a user's computer. This gives the virus the potential ability to add new code "on the fly," so to speak. The article claims the virus author can "effectively control the infected computer remotely." I'm not sure if this is a reference to the ability to upload new code to be executed, or if it literally means remote control of the machine; given the wording, I'm leaning toward the former. Nonetheless, it sure makes for a fun time. From the sound of it, the virus could (among other things) install a new, unknown virus that persists after the original one has been cleaned off the machine. Yay.
