Search Defense

What is Search Defense?

Search Defense from 50OnRed is an adware Internet toolbar/extension that will deliver ads to the browser on web pages that are not affiliated with the ads or the extension. Ads will be injected as new ads that would not normally appear or displayed on top of ads that the underlying website is already providing. These ads often direct the user to download potentially unwanted software or purchase products from affiliates. If a coupon is being displayed, clicking on any of the offers will result in a redirect that will drop affiliate cookies on to the end user computer and resolve the end user to the advertiser page/offer. Search Defense will communicate with a remote server in order to track the habits of the user including what domains the user visits, what pages they view and what advertisements are displayed and clicked on.
