Can't connect to Internet

Ever since updating my Norton Anti-virus I can't access the internet.  I've tried turning Windows firewall off and on , same problem.  I downloaded Install_Winsockxp.fix and got The instructions at "0x71578dad" referenced memory at "0x71578dad" This memory could not be read.

 

So here I am with hand out looking for help.  This is the first problem I've ever had with Norton and that goes back into the 90s.
