The NYTimes has an article today called "Geeks Put the Unsavvy on Alert: Learn or Log Off" about how viruses lately seem to be spread (or caught, depending on your POV) by the same people's computers over and over.

I wonder if libraries a serious vector for computer viruses. All those public terminals add up. I'll bet that a lot of libraries don't disable or remove email programs, leaving themselves open to viruses and all the maladies that go with them.
