Ad-Aware is by far the best adware remover I have ever used. Ever since the first days at which adwares and spywares began to occupy the internet, Ad-Aware was the pioneer to discover and remove the annoying threats.
Ad-aware 2007 is a new pro version that stays on the track. You can either choose to run a smart scan(scans all the critical sections of the system), full scan r custom scan. The search results identify critical objects from the others. In addition, You can schedule your scans to stay protected.
Besides, the most interesting feature is \"Ad-Watch\". With \"Ad-Watch\" monitors your computer in the background, and prevent malicious programs from being installed and taking control of your system.
