Have Dell Inspiron laptop running Windows 7 and the user after having Norton 360 v4.2 installed can not access the internet (yes, I have tried shuting down the norton firewall and it seems to shut down but, still no conection). Also every time you try to open a browser you get window asking if you want to use Internet explorer or windows meda center. If you pick explorer you get pop up window asking if you want to run, save or cancel, internet explorer. Pick run and goes back to first window. Pick meda and it opens up but, has no internet access. What gives. Oh and yes I can ping a internet site (google) but can not connect (or bring up the web page) of same.

Quick summary for and : because the laptop reaches the router and returns pings from the Internet but web pages fail and the behavior follows the machine to different networks, the problem is very likely local to that Windows install (browser/proxy/filters/associations) rather than the ISP or router.

Try these checks in order (fastest first):

  1. Test with a different browser (copy a known-good portable Firefox/Chrome to USB and run it). If pages load, the problem is IE-specific.
  2. Start Internet Explorer without add-ons: run iexplore -extoff. If that works, disable suspicious add-ons (especially any Norton/“web protection”) from Tools → Manage Add-ons.
  3. Check for a proxy (malware often sets one). In IE: Tools → Internet Options → Connections → LAN settings → ensure “Use a proxy server” is unchecked. Also run netsh winhttp show proxy to check the system proxy.
  4. Inspect the hosts file (open Notepad as Administrator and load C:\Windows\System32\drivers\etc\hosts) — remove any nonstandard entries redirecting web sites.
  5. Check the actual IE executable/shortcut: browse to C:\Program Files\Internet Explorer\iexplore.exe and double-click it. If you get a download/run/save dialog, file associations (.exe, .lnk or the HTTP/HTTPS protocol handlers) are likely corrupted; recreate the shortcut or consider a system repair.

Reset networking and common Windows stacks (run an elevated command prompt and reboot afterward):

netsh winsock reset
netsh int ip reset
ipconfig /flushdns
sfc /scannow

If the problem persists, boot into Safe Mode with Networking and test again (this disables many third-party filters). Also temporarily remove Norton (use the vendor’s remove/clean tool) to rule out its web-filter driver. If still broken, collect and post the outputs of ipconfig /all, netsh winhttp show proxy, and the hosts file contents so responders can pinpoint the next steps. Back up important files before doing restores or reinstalls.

How are you connected to internet?Are you directly connected to an ISP Modem or you have a Router between your laptop and ISP Modem?

Are you accessing internet using ethernet cable or wi-fi?
