In the run-up to April 1st I saw quite a bit of fairly hysterical coverage of the Conficker worm. Much of it appeared to be written by journalists who didn’t have much of a clue, or by concerned IT workers with limited communication skills. One of the things that most of these articles lacked was clear and reliable directions as to how to find out if you were infected. Sometimes us old folks who have been playing with PCs for decades are quite useful, and today my feed reader popped up Jerry Pournelle with some simple and sound advice. In particular he pointed to this web page, which uses an ingenious test to tell you very quickly whether your computer is infected or not.
The map of infections is fascinating as well. It is probably a very good proxy for a map of where in the world lots of people are online.
