Help Me!!!!!!!!

When i open my favorites there are some unwanted favorites.
They are for things like casinos and travel and green card lottery.
When you right click on other favorites it will give you maNY OPTIONS BUT WHEN YOU RIGHT CLICK ON THE unwanted items it only comes up with one option , close toolbar.
I have tried all youre suggestions but they dont seem to work.
My antivirus (Norton 2006) does not pick it up.

Please Help
Yours Sincerely
Bruno
