PornMag Pass, also known as Emcodec.d is an installer for the PornMag Pass application, which offers purportedly free access to certain adult magazines and related web sites. However, it is also a trojan that drops widely spread parasites such as SpywareQuake or SpyFalcon. Once executed, the threat displays the setup screen. Then it installs itself to the system along with another parasite. After a while, PornMag Pass executes that parasite.
