From this point of view, Internet Explorer is just like any other Win32-based program with its own memory space to preserve. With Browser Helper Objects you can write components—specifically, in-process Component Object Model (COM) components—that Internet Explorer will load each time it starts up. Such objects run in the same memory context as the browser and can perform any action on the available windows and modules. For example, a BHO could detect the browser's typical events, such as GoBack, GoForward, and DocumentComplete; access the browser's menu and toolbar and make changes; create windows to display additional information on the currently viewed page; and install hooks to monitor messages and actions.

Many times in order to remove a piece of spyware or for troubleshooting and diagnostic purposes, you'll have to start Windows in Safe Mode. While in Safe Mode, only specific programs and files needed to run the operating system are loaded. Some functions, such as connecting to the Internet, will not be active in Safe Mode and a standard video driver will be loaded causing a washed out look and a possible change in resolution. However, because just the essential programs and files are loaded in Safe Mode, this allows us to remove some spyware, adware, viruses and such that cannot be removed in Normal Mode. Follow the instructions below to Start Safe Mode for your specific version of Windows.
