So, just how prevalent are internet and email viruses? Well, apparently, they are so rampant, that not even the International Space Station is immune. That's right, the ISS, currently in synchronous orbit, hundreds of miles away, has got a virus.

A few laptops on the space station have come down with the W32.Gammima.AG worm. Now, I don't think that this means that NASA astronauts are busy playing online games (or does it), but it does demonstrate that no computer is really beyond the grasp of a virus as long as that computer is online or networked.

The biggest problem here is that such a high-profile infection is going to make virus-writers and wannabe virus-writers go crazy thanks to all of the press. When asked how bad the infection was, a NASA engineer said "I don't know and even if I did, I wouldn't be able to tell you for IT security reasons," - So there.
