Unable to access specific WEB SITES

New install of norton internet security 2012 however I am finding out I am unable to access some websites that I used to on regular bases.  to start with https://providentfunding.com/ and www.calottery.com and I get the following message after few moments:

"Internet Explorer cannot display the webpage"  I have tried to disable all options but still no go unless I deinstall the product completely.

I am using IE 8, Win 7, SP1 on a fast computer from home.  trying google chrome did not make a diffence either.

 

any ideas??
