I cannot perform a web update of the Definition File after upgrading Ad-Aware SE; there is an error in retrieving the update.
This problem may be caused by one of the following factors:
The Definition File on your system might be corrupt. To check, locate the directory "C:\program files\lavasoft\Ad-Aware SE\ folder." Delete the files "defs.ref" and "def.ref.old." Try to update again.
If the update stops after only five percent is processed, your firewall is most likely preventing the update. To correct this, disable the firewall for the duration of the update or configure the firewall to allow requests from Ad-Aware SE to pass through.
Web update confirmation dialogs are suppressed. To correct this:
Open Ad-Aware SE.
Click the "Ad-Aware SE Configuration Window" icon.
Click "Tweak."
Click on "Web Update Settings" to expand it.
Deselect "Suppress Web Update confirmation dialogs."
You have inadvertently turned on the "Use HTTP Proxy" option. To correct this:
Open Ad-Aware SE.
Click on the "Integrated Web Update Tool" icon.
Click on "Configure."
Deselect the "Use HTTP Proxy" option.
Try updating the Definition File again.
If none of the above is preventing the update, we recommend that you try performing a manual update. To do this:
Close Ad-Aware SE.
Download the latest Definition File in ZIP format here
http://download.lavasoft.com/public/defs.zip and save the file to a temporary location.
Unzip the contents of the file either with a ZIP utility or with the built-in support in Windows to the Ad-Aware SE installation directory, which usually is "C:\Program Files\Lavasoft\Ad-Aware SE\".
Open Ad-Aware SE.
Confirm that the latest Definition File is installed by checking the "Initialization Status" in the main program window.
