What is Browser Helper Object, BHO

remove bhoA Browser Helper Object (BHO) is a DLL module designed as a plugin for Microsoft’s Internet Explorer web browser to provide added functionality. BHOs were introduced in October 1997 with the release of version 4 of Internet Explorer. Most BHOs are loaded once by each new instance of Internet Explorer.

BHO, just like the addons, enhance the functionality of Microsoft IE and make it feature rich.

BHO seldom requires permission before performing further actions, hence it easy for malicious coders to conceal the actions of their browser addons.
