Could be the Code Red [123] Worm. If the entry is a request for 
"default.ida" with a whole bunch of garbage afterwards, it's 
the worm. Of course, as an Apache user you have nothing at 
all to worry about. :) Check the fourth to last field for the code 
that the browser returned. If it's a 400 series, then you should 
also have a line in the error_log. (This code comes right after 
the GET request.) For example, here are two recent entries 
from my access_log:

(the actual requests are hundreds of characters long, trimmed 
to save space)

207.197.158.22 - - [23/Aug/2001:03:50:38 -0400] 
"GET /default.ida?XXX%u909%u00=a  HTTP/1.0" 403 273 "-" "-"

212.213.219.229 - - [23/Aug/2001:07:01:26 -0400] 
"GET /default.ida?XXX%u00=a HTTP/1.0" 404 1589 "-" "-"


Both have 400 error codes (access denied and file not found) so show up in 
the error log as well. In the future, please 
go ahead and post the relevant line from the access_log 
to the list (edited for privacy if you wish), as all of this 
is only a guess. :)
