China, Thailand and Taiwan leading the world in malware

And those are the countries that widely implement Carrier NAT, and whose residents generally struggle to afford a computer at all.

Carrier NAT means instead of one residence having an IPv4 address, the address is instead shared by over 100 customers. One of them transmits a virus or spam email, how do you know which one it was? You going to log each and every IP datagram?

If the world just pushes forward with Carrier NAT, I can see us looking back to this day, and thinking 50,000 viruses a day being small!

That, and I think Microsoft's attempts in dumbing down the OS rather than improving the security model is a big factor too. I wonder what OS we'd have from them today, if intead of buying QDOS all those years ago, they instead picked up their in-house developed Xenix OS and used that as the basis for the OS for the IBM PC.
