AntiVermeans is a trojan that displays an icon in the system tray. This icon shows a message saying that the compromised computer is infected with dangerous viruses and asks the user to download and install a removal program, which actually is AntiVermeans, the same named corrupt illegally distributed spyware remover. Once the user clicks on that message, the trojan opens a web site distributing AntiVermeans. It may also attempt to download the application without asking for user permission. The trojan is able to change the Internet Explorer default home page, redirect the web browser to malicious web sites, download and install other parasites. AntiVermeans automatically runs on every Windows startup.
