On a client's computer running Vista x86, he installed Norton Internet Security 2011, and the Internet stopped working. I took a look, and Internet Explorer and a fresh copy of Firefox are not connecting. I can ping addresses (such as www.google.com and msn.com), and I get the same replies back on that computer as a second computer on the same network. I uninstalled Norton, and both browsers started working. I tried a fresh download from the Norton website, installed it successfully, but still blocks the Internet.
The copy has NOT been activated yet, but I have a valid key with his receipt when he purchased it from Symantec. It has not asked for a key, but it's passed its period of working where it now wants it activated. Of course, with no Internet, it doesn't activate
