I guess this is why botnets and spam-zombies are dragging down the internet - nobody takes 5 seconds to follow appropriate security measures.

Amen. The majority of my time is spent cleaning machines
for people that just keep going to the same porn sites and
downloading the same cute little freeware helper apps that
install 5 other apps when you install it. Windows security
(or lack of) and user ignorance is what allow things like
these to thrive. I'm glad to see these changes.
