Does it really take a rocket scientist to install an anti-virus app and keep it up to date? If the astronauts aboard the International Space Station are any indication, even that's not enough!
Apparently, earlier this month NASA detected that a worm had infected some computers that were taken up into orbit in July. Smart as astronauts have to be, it seems none of them thought to even install an AV program on their laptops.
Fortunately, the virus in question is only designed to steal passwords for some MMOs popular in East Asia, so shouldn't do any real damage while it is investigated and contained (if the astronauts do play those games, the lag from space might be a bit too much...).
On the upshot, now you can say you're smarter than an astronaut simply by keeping your AV on and up to date
