A '''Browser Helper Object''' ('''BHO''') is a [[Library (computer science)|DLL]] [[Module (programming)|module]] designed as a [[Plug-in (computing)|plugin]] for [[Microsoft]]'s [[Internet Explorer]] [[web browser]] to provide added functionality. BHOs were introduced in October 1997 with the release of [[Internet Explorer 4|version 4]] of Internet Explorer. Most BHOs are loaded once by each new instance of Internet Explorer. However, in the case of [[Windows Explorer]], a new instance is launched for each window.
 
BHOs is still supported as of Windows 10, thoughthrough [[Internet Explorer 11]], while BHOs is not supported in their default web browser [[Microsoft Edge]].
