The initial program I removed was Symantec's Norton Antivirus
Joe, Just took another look at post #8, and everything looks good except
1. I see you haven't disabled IPv6 on either adapter, try that and reboot
2. I see that your ip addressing scheme is using your router for default DNS resolution, try setting it manually to 8.8.8.8 preferred and 8.8.4.4 alternate just to see if it's having a problem forwarding. Reboot again
The reboots shouldn't be necessary, but they won't hurt
It could be a problem with malware or a virus, but it sounds a little like IE8 privacy, security or more likely someone has mucked about with the content advisor settings. Try opening IE and go to tools, internet options and on the advanced tab choose restore advance settings and then click the reset button and make sure you select to get rid of everything and see if that makes any difference.
