Fmovies is one of the most popular pirate sites on the internet yet over the last three months the site has still managed to grow at an extraordinary rate. In May, Fmovies serviced around 98 million visitors but in July, in excess of 122 million called in for the latest movies and TV shows. How many users are affected isn't clear but over the past 48 hours a sudden flurry of malware alerts have had some site users spooked.
