And yet blaster type worms are less common now, and I still get the 
occasional reinfection reported where a computer shop installs XP 
pre-patch with a public IP. A simple stateful firewall or NAT router 
would stop that and allow them to finish patching the OS. There is 
always a new attack vector.
