Sick of those pesky pop-up screens?
If an advertiser can gain sufficient access to your system to perpetrate this kind of brazen resource theft, so too can a self loading worm. Think of the pop-up screen as a worm.
Technically, a pop-up screen is a worm: It arrives at your web browser and without so much as asking your permission, launches itself on your system. In the case of advertisers, your access to your own system is hindered, and a substantial proportion of your system resources are commandeered, without payment for the "borrowed" machine time. In some cases, careless advertisers launch so many popup screens on your system that they choke off your internet connection and may even cause Windows to fail in extreme circumstances. Hackers (the criminals who create viruses and worms), however, will take things further: Much further.
DrawBridge is designed to disable the client-side technology exploited by criminals and advertisers alike to get viruses, worms, and spyware into your system. An unintentional but very satisfying side-effect, is that most pop-up adds are disabled as well because these depend on the same security holes as hackers do.
