While I agree with your first two items, I disagree that they are mutually exclusive nor that the list is exaustive. The last statement about "days of truly brilliant, and capable, virii are gone." further shows you don't know what your talking about (in this case, not a general observation

)
I'll extend your list:
3) Blackmail/extortion
4) Offensive/defensive military operation (anyone remember the Gulf war laser printers?)
5) Research (albeit frowned upon by those truely researching this area)
6) Sales tool (eEye wasn't too crushed regarding their sales when CodeRed hit)
