* Unlike businesses with permanent security staff, most home users are slow to secure their computers with the latest antivirus and firewall software and to plug security holes by downloading the necessary fixes from software makers such as Microsoft Corp.

That should be qualified, you know: *small* businesses do not have security staff, nor particularly qualified network admins. When sharesniffing around, I found the 8 to 256 size netblock to be the most profitable; larger netblocks implied more clueful admins. Pax
