Can't reset homepage

I have been having a Norton page pop up when I go online with the following message:  "A malware threat was detected by your Symantec security product. The malware maliciously changed your browser's home page. Your Symantec security product detected and removed the malware to protect your system. Because the Symantec product cannot determine what your home page setting was before the malware attack, it has sent you to this Web page. Please use the orange button below for instructions on how to reset your browser's home page to a Web page of your choosing."

Reset Your Home Page  The link does not work though, nothing happens when I click on it.. What should I do?  If I try setting a home page from a web page like Comcast.net, all I get is this same message from Norton. Any help is appreciated.
