Hi Blom/Jb,
From a similar FAQ (on the forum)
Ad-Aware Definition Update Problems are instructions for a Manual Update. Step 3 details the simple steps:
"3. If the first 2 methods do not work, then you should try a manual update.
Update the definition file by downloading the zipped definition from
http://download.lavasoft.com/public/defs.zipUnzip this file and you will get a "defs.ref" file. This file should be copied to "c:\Program Files\Lavasoft\Ad-Aware SE\" (the folder name will changed depending on if you have pro / plus / free)
Now load Ad-Aware. If the definition file is still showing your old one, then click on the settings icon (the cog wheel), then click "General". At the bottom right, there is a box saying "Using Definition File". Click the "Open file" icon next to that box and then browse to the definition file in "c:\Program Files\Lavasoft\Ad-Aware SE\" (the folder name will changed depending on if you have pro / plus / free) Select it and press open. You should now have the latest version." (ie:
SE1R145 17.01.2007 )
Once the Definitions are up-to-date, using the normal "WebUpdate" method should work again.
Let us know how you get on.
Regards,
Spike
