Certain websites on the Internet require additional software called add-ons to work properly. While many of these add-ons are beneficial, some can slow down your browsing speed or even be malicious tools used to exploit security loopholes in your web browser. If you have acquired a malicious add-on to the Internet Explorer version 8 web browser you can remove the add-on using the browser's add-on manager.
Internet Explorer 8
Click the "Tools" icon at the upper-right end of the Internet Explorer window. Scroll down and select "Manage Add-Ons."
Select "All Add-Ons" underneath the "Show" heading. Scroll through the list of currently installed add-ons and find the specific entry you want to remove.
Click the name of the add-on and select "Disable." Repeat the process with other malicious add-ons you want to remove.
Click "OK". Close the Internet Explorer web browser, and open it again to save the changes.
