A method and system to selectively secure the display of advertisements on web browsers, defining a particular displayed area of said interpreted markup file, obtaining the DOM tree of said interpreted markup file, said DOM tree comprising parent and child nodes; each node being associated with displayable elements, identifying in the DOM tree a set of child nodes whose displayable elements comprise said particular displayed area, identifying in the DOM tree a first parent node comprising said set of child nodes, converting displayable elements associated with said identified first parent node to an image, generating a second parent node comprising said image, modifying the DOM tree into a modified DOM tree by deleting said identified set of child nodes and by replacing the identified first parent node by the second parent node.
