…Notes…

Privacy is, in many ways, more important than security. Hacked systems that have damaged files or are overrun by viruses can be reformatted and reinstalled. The loss of trade secrets and personal data can do irreparable damage to a company’s (or an individual’s) reputation.

CONTROLLING ADD-ON PROGRAMS

Add-on programs and ActiveX controls extend Internet Explorer.

Browser helper objects (BHOs) control browser operation.

You can manage add-ons and BHOs with Add-On Manager.

Chapter 12: MANAGING INTERNET EXPLORER CONNECTIONS AND SECURITY 30

More Detail…

Browser add-on applications and BHOs are designed to extend and control the capabilities of Internet Explorer. They also can be designed to control Internet Explorer for malicious purposes. Many forms of Internet spyware are add-ons or BHOs.

Add-On Manager helps control the add-on and BHO applications on a system. If time permits, demonstrate using Add-On Manager. Describe how it is used to disable BHOs and other add-ons.
