Norton 360 V5 blocks internet access when installed

I have tried uninstalling the product through Control panel and then using Norton removal tool to remove all files from the system but when Norton 360 is installed the computer cannot get access to the internet the hardware connects just fine just no traffic

the computer is windows vista sp2 

I have verified that when Norton 360 not installed the internet connection works just fine but when it is installed it cannot connect to any site through any program 

the windows firewall is off and in the options for the firewall in 360 are block all network traffic toggle is on unblocked

Please help

Do you have Microsoft Security Essential installed? If yes, remove it. There are chances that MS Essentials blocks connectivity when installed with Norton.

 

If you do not have MS Essentials installed, then try disabling Norton's Smart Firewall and see whether you can connect to the Internet.

 

What is the make and model of your router?
