Removing BHO's in Microsoft AntiSpyware:
To view the BHO report:
1. Click "Tools" - "Advanced Tools" - "System Explorers".
2. In the left pane, underneath "Internet Explorer", click "IE BHOs".
You will see a list of installed Browser Helper Objects. As noted in the
key, BHOs preceded by a star should be safe, those next to an exclamation
point are unknown, and those next to a red "X" are those Microsoft
AntiSpyware deem hazardous.
Click a BHO for more detailed information if available, such as the BHO
name, description, and publisher name. Also, in the right pane, you can
choose to temporarily or permanently block the BHO. If the BHO is hazardous,
you may want to consider permanently removing it. However, for unknown BHOs,
you may want to consider only temporarily removing the object and examining
the effects later from within Internet Explorer.
