Over 80,000 Google Chrome browser users have been hit by a fake, malware infected, version of Rovioís Bad Piggies that is attracting users because it is free. The malware was detected by Barracuda Labs who warned users about a free web-based version of the game found on the official Google Chrome web store that carries the title Angry Birds Bad Piggies. According to Barracuda Labs, the app installs an ad injector that replaces original ads on sites including Yahoo, MSN and others, instead promoting other products.
