Correction 1: In the past the vast majority of attacks didn't spread as far and as fast as MyDoom. That's no cause for complacency. I think we can expect a lot more rapid-spreading viruses in the future. Correction 2: Antivirus vendors weren't that fast in getting updates out for MyDoom.A.

Consider also that some vendors still work on a weekly update cycle (e.g. McAfee) with updates more frequently only when a virus is detected in some numbers in the wild. Bolting stable doors...
