I am running an HP Pavillion TS 11 Notebook PC with Windows 8.1 with AMD A6-1450. I am connected through my WIFI internet, but cannot bring up any web pages. My ISP tried everything, but my other computers in the house all have no problem. I was in the process of downloading a new version of Norton. It said it removed the old version but could not connect to download the new version. I closed the Windows Firewall.
