What? This is the most ridiculous thing I've read in the past month.<p>Extraterrestrials would have to target specific buffer overflow bugs or something in SETI executable code, which to know about, basically means they're already visiting Earth in UFO's and walking around NASA as spies. And if they're already doing that, I don't think they need to create a computer virus to accomplish their goals.<p>There's no such thing as a "general" computer virus. Viruses are OS/program-specific.<p>This article/headline is pure science fiction, and pretty bad fiction at that.
