How do botnets still exist? Wasn't that a problem that should have gone away with Windows XP?

Devices running Windows XP aren't the only ones that can be compromised. Other possibilities are unpatched Linux servers, servers with easily guessed root passwords, consumer routers, etc.

Windows XP hasn't gone away.

So are the botnets that still exist mainly running on the legacy XP boxes?

It says here that it's roughly 10% of machines. It's safe to assume at least half are infected. But aren't they mostly third world?
