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.
Vundo is often distributed as a DLL file and installed on an affected machine as a Browser Helper Object (BHO) without a user's consent. This family uses advanced defensive and stealth techniques to escape detection and to hinder removal.
For more information, please see the Win32/Vundo analysis elsewhere in the Microsoft Malware Protection Center encyclopedia.
Alert notifications or detections of this malware from installed antivirus or security software may be the only other symptoms.
