Twist in the worm: Conficker threat unchanged

Even if it's not an April Fools' joke, the latest moves by the dreaded Conficker worm are by no means an Internet Armageddon, either.

The worm's alarming outbreak entered a new phase yesterday as clocks around the world ticked into the first day of April, the day it was scheduled to change programming.

But security experts appeared correct in their predictions that the day was likely to come and go without any major disruptions, even though the worm has infected anywhere from 3 million to 12 million PCs.
