Summary
Trojan:Win32/Vundo.EL is a component of Win32/Vundo, a multiple-component family of programs that deliver 'out of context' pop-up advertisements. They may also download and execute arbitrary files. Win32/Vundo is often distributed as a DLL file and installed on a computer as a Browser Helper Object (BHO) without a user's consent. The Vundo family uses advanced defensive and stealth techniques to escape detection and to hinder removal.
