I was of the "hype" opinion well over a week ago in this thread:

Certain companies reporting the high number of emails with the MyDoom and high expansion rates (help sells their AV), but not reporting the number of actual computers infected by opening the attachment, and not really knowing.

I still say the "LOVE BUG" would be the biggest ever that infected computers based on a percentage chart giving the number of computers operating world wide at the specific given time. That one tugged at the heart strings of romance, and no female (and most men)at the time could resist opening the attachment if they receive it in a email.
