It seems like half the sites I visit have now have suddenly become infected with these bloody Infinityads that pop up as soon as you begin reading a page and you can't get rid of the fucking things. Clicking close makes the screen blank and does not return to the main page. This is not good for my blood pressure and I am not far away from chucking my mac through the window. Anyone know how I can get rid of them and return to the page I am trying to read????
