There could be a brick like there was in the early stages on DS homebrew, which would be an extreme annoyance, and there would be a debricking method. This would also be when the 3DS gets hacked, if it does, in fact, get hacked.
I honestly don't think that there would be a virus. A virus would require, as above, the ability to run unsigned code, and that would be only if the 3DS gets hacked.
