Elfman,
Please can you make sure that it is
Ad-aware SE Build 106 that you have.
[if not Uninstall your old Ad-aware first then install SE] now you can disable that notification by opening d-aware then click on the settings tag (The Gear) and then un-tick the option that says
"Prompt to update outdated definitions consider definition outdated after **" then click th proceed button.
But I recommend that first you open the Ad-aware folder on your "C" Drive and rename the
defs.ref to say
old defs.ref then try downloading the Definition file again.
