Zombies like peeping in

When I read this article about 'Zombie' machines, I knew somewhere along the way one well known fact would pop up.

*Scans paragraph* "More than 450,000 computers are now part of zombie networks ..."

*Reads some more* "Most spam or junk mail is routed through the hijacked machines forming a botnet...."

Wait for it, wait for it ... there it is.
The vast majority of machines in these botnets will be PCs running a version of Microsoft Windows.

Some people never learn.
