Wait. If you already know what happens when you click on those ads, why did you do it again? For old times sake? Anyway, I think you should just chalk this up to more experience and visit as many porn sites as you can in the next 20 minutes and see how long it would take to stop your computer completely. At least you can have some frustrating fun along the way, ''Ohhhhhh come on load already.. ooo wait just a couple more pixels!...''
