It was a wonderful Xmas – not only from a PC resellers point of view. Old computers were exchanged and brand new
preinfected preinstalled PCs were installed. As Windows XP now comes with at least SP2 and the mandatory firewall, those boxes are slightly more secure. A nice side effect is, that the new (unpatched) computers replaced the old (infected) ones. The global number of bots has decreased.
Sadly it is only a matter of time and (ir)rational users until everything starts all over again.
