What is NetCrawl?

NetCrawl is an adware program from Yontoo that integrates into the user's web browsers (IE, Chrome, Firefox) and will perform a number of functions mostly designed to generate advertising supported or affiliate revenue. In order to do so the program will display a number of different ad formats by injecting the ads directly in the user's browser based on either the activity of the user's past and present behavior or based on the context of the web page. Ads are displayed as banners, text-links, search related adverts or in many cases malvertising in order to get a user to download and install additional software, mostly bundled adware. This adware will also track and report back the user's surfing behavior including web pages and domains visited as well as the advertisements displayed and clicked.
