Yeah.. The default def file is out of date.. AdAware's update thing is bit wack, but it's worth going through a few hoops for. Download this, http://www.lsfileserv.com/aaw/binary/refupdate.exe

Here's where my friends got confused.. They downloaded it, ran the setup and thought AdAware was now updated. However, this just installs the updater util, you now need to go to Start->Programs-> etc and run the program, it will connect and download the lastest ref file.. and viola!

I know.. it's convoluted.. but it works.
