Browser Helper Objects (BHO's) are additions to your internet browser that often appear as browser toolbars or add-ons.
 

Managing Browser Helper Objects:
 

  1. Select the Optimize tab, then click the Browser Object Manager button.
  2. From the list of Browser Helper Objects, please put a check mark next to any you want to enable.
  3. Remove the check mark next to any objects you wish to disable.
     

You can also use the Enable All or Disable All buttons to turn all browser objects on or off.
 

If there are items you are unsure about, try searching for that program on Google. Any legitimate Browser Helper Object should have a website created by the developer to provide more information.
