For those who are still using Ad-Aware SE Pro or personal but as all of us discoverred that the Integrated WebUpdates Tools of the definitions is no longer working through the auto-update, here is a script which will help you installing the new definitions as they are provided.

Hope it will help Ad-Aware SE users ...

#!/usr/local/bin/perl

#
# (c) J. Lauret July 2008, GPL
#
# This script contacts the LavaSoft update center, checks if updates
# are available for the Ad-Aware SE definition files, downloads and
# install the update if needed. It is a replacement for the automated
# updates for Ad-Aware SE (product support for definitions continues
# but the update center mechanism was broken).
#
# This script is meant to run under cygwin on Windows.
#
# Variables used (and you will need to change) are:
#   $ARCH   An archive directory for the downloaded packages specified as
#           cygwin-path syntax.
#           *** YOU HAVE TO DEFINE THIS ONE FOR SURE ***
#
#   $TRGTD  Target directory where your Ad-Aware SE product is installed
#           There should be no need to change this unless you have it
#           installed on another drive than the C: drive
#
#   $ENAM   Lavasoft package name for the definitions (assumed to be
#           $ENAM.zip)
#   $BNAM   The base name of the definition files to be downloaded and
#           archived on your disk (no need to change unless you really
#           do not like the name I picked). If not defined, will default
#           to $ENAM
#
# In case
#   $SRC    Source and base URL where the defs.zip can be found.
#
