Tried to install Nod32 ANTIVIRUS; had to remove preloaded Norton antivirus trial; when Norton was uninstalled, we lost internet connection.  DSL coming in does work on a separate laptop we tried.  Seems to be a problem within the computer.  Tried system restore - didn't work.  Tried to have computer diagnose the problem - could not resolve problem.  Under network and sharing center, there is a red "X" before the globe.  Any ideas?  Did you use the Norton Removal Tool ? ?I followed the uninstall instructions on the NOD32 download.  Then I WENT to the Norton site under "Programs" and clicked "uninstall".Run the removal tool and re-boot.Since I uninstalled Norton, I can't run anything for Norton.  Since I don't have the internet connection, I can't get the Norton removal tool.  Seems to be a MUCH bigger problem - somehow the computer is not reading the connection to the internet.  I have made some calls to have an "expert"who is gonna take the computer and to try to fix it.  Thanks for trying to help me out of this mess.Make sure you have uninstalled all the security software and try to connect to a different Inet connection if possible. if it works, it just the SETTINGS for your DSL provider you have missed. could be set to a specific IP.  DO NOT connect to the internet after removing all security software - that is terrible advice.you can try unistalling the NIC (network interface card) and rebooting you system. the driver will reinstall after the reboot
