The Zlob Trojan, also known as Trojan.Zlob, is a trojan horse which masquerades as a needed video codec in the form of ActiveX. It was first detected in late 2005, but only started gaining attention in mid-2006. Once installed, it displays popup ads with appearance similar to real Microsoft Windows warning popups, informing the user that their computer is infected with spyware. Clicking these popups triggers the download of a fake anti-spyware program (such as Virus Heat and MS Antivirus (Antivirus 2009)) in which the trojan horse is hidden.
