GoodTab Class (suptab.dll) works like an Adware virus – in that it generates Advertisements (Ads) and harasses you with them. The Ads will be created whenever you start your browser or load a new page/tab/link in it. The Ads will come in the form of pop-ups, banners or even whole pages filled with Ads to the brim.
