Re the BlackWorm/Kama Sutra/Nyxem video: The rate of infection for BlackWorm didn’t match the actual amount of machines that had destructive results on the 3rd. Remember, this is the worm that was supposed to kill a lot of machines (estimates were that approximately 300,000 systems were infected) on February 3rd.
– The amount of machines that were really infected still on Friday was much smaller than the total amount of machines that got infected (and cleaned) during the whole outbreak. This number is probably in the tens of thousands. Which is not a lot of computers out of, say, one billion computers in the world.
– Many of the infected machines were not rebooted on Friday. They were simply running all the time. The worm only does damage when you start the machine on the 3rd.
– Many infected home machines were shut down all of Friday, and nothing happened. People went to movies, bars, parties on Friday night instead of surfing.
– The media coverage on the whole incident prompted many people to check their system and clean them up in time.
