Can a Dreamcast catch a virus?

Been in the back of my head for a little, can a Dreamcast catch a virus? I'm guessing not, nobody's coding their viruses for the potential dude who finds it on a Dreamcast. Maybe older viruses have an effect, but even then I'm still skeptical to their capabilities.

So, can a Dreamcast catch a virus?

If coded properly, yes, but only one that could shut it off, and only through downloading a vmu file, however barely anyone knows how dlc works so a virus is highly unlikely

I have BBA advantage!
