IE 7 HomePage Does not Stay in Internet Options

[twe]

I had AntiVirGear and ran Smitfraud file and got rid of the alerts but now a blank page send me to a 'Security Web site' at http://thesafetyfiles.com/. I can not remove this re-direct and can not put my 'home page' in the internet options page. My preferred web page does not stay, it is over written by a blank page and sends me to the above site.

I tried resetting my options on IE7 but did not fix problem.

Any advice?

Thanks,
