</header>

<p>A <b>Browser Helper Object</b> (<b>BHO</b>) is a <a href="Library_(computer_science)" class="mw-redirect" title="Library (computer science)">DLL</a> <a href="Module_(programming)" class="mw-redirect" title="Module (programming)">module</a> designed as a <a href="Plug-in_(computing)" title="Plug-in (computing)">plugin</a> for the <a href="Microsoft" title="Microsoft">Microsoft</a> <a href="Internet_Explorer" title="Internet Explorer">Internet Explorer</a> <a href="Web_browser" title="Web browser">web browser</a> to provide added functionality. BHOs were introduced in October 1997 with the release of <a href="Internet_Explorer_4" title="Internet Explorer 4">version 4</a> of Internet Explorer. Most BHOs are loaded once by each new instance of Internet Explorer. However, in the case of <a href="Windows_Explorer" class="mw-redirect" title="Windows Explorer">Windows Explorer</a>, a new instance is launched for each window.

</p><p>BHOs are still supported as of Windows 10, through <a href="Internet_Explorer_11" title="Internet Explorer 11">Internet Explorer 11</a>, while BHOs are not supported in <a href="Microsoft_Edge_(series_of_web_browsers)" title="Microsoft Edge (series of web browsers)">Microsoft Edge</a>.

</p>

<div class="mw-heading mw-heading2"><h2 id="Implementation">Implementation</h2></div>

<p>Each time a new instance of Internet Explorer starts, it checks the <a href="Windows_Registry" title="Windows Registry">Windows Registry</a> for the key <i>HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Browser Helper Objects</i>. If Internet Explorer finds this key in the registry, it looks for a <a href="Universally_unique_identifier#In_COM" title="Universally unique identifier">CLSID</a> key listed below the key. The CLSID keys under Browser Helper Objects tell the browser which BHOs to load. Removing the registry key prevents the BHO from being loaded. For each CLSID that is listed below the BHO key, Internet Explorer calls CoCreateInstance to start the instance of the BHO in the same process space as the browser. If the BHO is started and implements the IObjectWithSite interface, it can control and receive events from Internet Explorer. BHOs can be created in any language that supports <a href="Component_Object_Model" title="Component Object Model">COM</a>.<sup id="cite_ref-1" class="reference"><a href="#cite_note-1"><span class="cite-bracket">[</span>1<span class="cite-bracket">]</span></a></sup>

</p>

<div class="mw-heading mw-heading2"><h2 id="Examples">Examples</h2></div>

<p>Some modules enable the display of different file formats not ordinarily interpretable by the browser. The <a href="Adobe_Acrobat" title="Adobe Acrobat">Adobe Acrobat</a> plug-in that allows Internet Explorer users to read <a href="Portable_Document_Format" class="mw-redirect" title="Portable Document Format">PDF</a> files within their browser is a BHO.

</p><p>Other modules add toolbars to Internet Explorer, such as the <a href="Alexa_Toolbar" class="mw-redirect" title="Alexa Toolbar">Alexa Toolbar</a> that provides a list of web sites related to the one you are currently browsing, or the <a href="Google_Toolbar" title="Google Toolbar">Google Toolbar</a> that adds a toolbar with a Google search box to the browser <a href="User_interface" title="User interface">user interface</a>.

</p><p>The Conduit toolbars are based on a BHO that can be used on <a href="Internet_Explorer_7" title="Internet Explorer 7">Internet Explorer 7</a> and up. This BHO provides a search facility that connects to <a href="Microsoft" title="Microsoft">Microsoft</a>'s <a href="Bing_(search_engine)" class="mw-redirect" title="Bing (search engine)">Bing</a> search.

</p>

<div class="mw-heading mw-heading2"><h2 id="Concerns">Concerns</h2></div>

<p>The BHO <a href="Application_programming_interface" class="mw-redirect" title="Application programming interface">API</a> exposes <a href="Hooking" title="Hooking">hooks</a> that allow the BHO to access the <a href="Document_Object_Model" title="Document Object Model">Document Object Model</a> (DOM) of the current page and to control navigation. Because BHOs have unrestricted access to the Internet Explorer event model, some forms of <a href="Malware" title="Malware">malware</a> (such as adware and spyware) have also been created as BHOs.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup><sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>

</p><p>For example, the <a href="Download.ject" title="Download.ject">Download.ject</a> malware is a BHO that is activated when a secure <a href="HTTP" title="HTTP">HTTP</a> connection is made to a financial institution, then begins to <a href="Keystroke_logging" title="Keystroke logging">record keystrokes</a> for the purpose of capturing user passwords. The <a href="MyWay_Searchbar" class="mw-redirect" title="MyWay Searchbar">MyWay Searchbar</a> tracks users' browsing patterns and passes the information it records to third parties. The <a href="C2.LOP" class="mw-redirect" title="C2.LOP">C2.LOP</a> malware adds links and popups of its own to web pages in order to drive users to <a href="Pay-per-click" title="Pay-per-click">pay-per-click</a> websites.

</p><p>Many BHOs introduce visible changes to a browser's interface, such as installing toolbars in <a href="Internet_Explorer" title="Internet Explorer">Internet Explorer</a> and the like, but others run without any change to the interface. This renders it easy for malicious coders to conceal the actions of their browser add-on, especially since, after being installed, the BHO seldom requires permission before performing further actions. For instance, variants of the ClSpring trojan use BHOs to install scripts to provide a number of instructions to be performed such as adding and deleting registry values and downloading additional executable files, all completely transparently to the user.<sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">[</span>4<span class="cite-bracket">]</span></a></sup>

</p><p>In response to the problems associated with BHOs and similar extensions to Internet Explorer, Microsoft debuted an <i>Add-on Manager</i> in <a href="Internet_Explorer_6" title="Internet Explorer 6">Internet Explorer 6</a> with the release of <a href="Windows_XP#Service_Pack_2" title="Windows XP">Service Pack 2</a> for <a href="Windows_XP" title="Windows XP">Windows XP</a> (updating it to IE6 Security Version 1, a.k.a. SP2). This utility displays a list of all installed BHOs, <a href="Browser_extension" title="Browser extension">browser extensions</a> and <a href="ActiveX_control" class="mw-redirect" title="ActiveX control">ActiveX controls</a>, and allows the user to enable or disable them at will. There are also free tools (such as BHODemon) that list installed BHOs and allow the user to disable malicious extensions. <a href="Spybot_%E2%80%93_Search_%26_Destroy" title="Spybot – Search & Destroy">Spybot S&D</a> advanced mode has a similar tool built in to allow the user to disable installed BHO.
