Everybody's reporting this article as James Gosling claiming Unix is immune to virii. By the article's words he's saying that Unix and its variants are less susceptible, but certainly not immune. And Gosling isn't stupid enough to have forgotten about the Morris Internet Worm exploit to the sendmail buffer overflow. The issue is when you write an operating system that invites attacks; Unix at least thinks about such things on the front end.
