Ad-Aware detects previous installations and offers to uninstall them for you and follows up with a fresh install with only a few clicks needed from the user. Ad-Aware SE then offers to update your definition file, show you the newly revamped help file and launch the program, where it automatically does the first scan for you. Ad-Aware does a brilliant job of retaining the same look and feel of the Ad-Aware you are familiar with, but does so with a completely rewritten engine, updated buttons, icons and the use of fonts.
