i hate this mess. i recently uninstalled norton av and none of my network connections would not come back no wireless no lan. i'm lucky that i have a few other computers to use at home and was able to search the web for a fix. come to find out that it had installed 2 registry keys that made dhcp and another network related service dependant on it being on the system

once i removed those keys and rebooted it was all good.. but there is another problem its installed on the other computer i used to find the fix. i swear use there product and they want u committed...lol
