I do not know if this article really speaks about the first Mydoom incident (some numbers look really strange and the results are totally different from what I know) but this is a main source of the original response test which contains avast! as well.
BTW: I have found this article which discusses the average response time for four virus outbreaks. While you might argue about the number and selection of those viruses (some started very quickly while others not) it is still interesting reading - and avast! beats Sophos, Dr.Web, Trend Micro, Panda, MsAfee and Symantec in this comparison
!
And another BTW: avast! times should be even better, because the testers use the VPSUPD.EXE file to update their scanner. This file is however uploaded on our web site maybe 20 minutes after the incremental iAVS update is released (it does not have such high priority and it takes some time to manage and update all our servers).
