What is webporpoise?

webporpoise is a potentially unwanted adware program that injects ads into the user's browser. This includes inserting into web pages or displaying ads over parts of existing web page advertisements, banners, coupons or text links that would not otherwise appear. It will communicate with the Yontoo's servers to check for new offers and the placement of offers as well as monitoring and recording the domain name of each page the user views, the advertisements that appear on these pages and the ads the user clicks on.
