Checking back the first XXXX one I saw was about 9 hours ago, since then
the number of XXXX and NNNN accesses has been about even. Actually
checking other logs I would say XXX accesses are the majority (over 80%)
in the last 4 or 5 hours.

I would guess a better version, perhaps it deletes the old Code Red copy
when it infects a machine which enables it to grow so fast.
