One time I was playing an online game and the next second a pop-up come up saying "Would you like a free penis or breast enlargement. If so click here" right and so I click on it to see were I would go. When the page loads it took me to a gothic site and then I got FREAKED OUT  . I exit the pop-up and the online game website lead me to WinCustimize. If you think I am making this up off the top of my head, think again. Post bellow if something similar happend to you.
