Significantly, for its propagation, cyber-criminals create Web-pages of movie trailers which instruct end-users for loading one browser plug-in. Indeed, according to the security researchers, a usual message is mimicked in the instruction that gets exhibited during the requirement of loading a plug-in alternatively of conducting an extra configuration.
