Cannot Browse the internet

I have a Dell laptop and I cannot access the internet. I have added a new admin account, tried IE7 and Firefox. Uninstalled IE6. Reset the Winsock. Repaired the Network connection. I can ping by address and by name. I can connect to update things such as ad-aware. I have disabled the Windows firewall and the McAfee security center. The browser will only connect to my bank login page a https: site. any http site won’t connect. I have also disabled all startup items in msconfig. I can’t get to any regular website. HOWEVER, I can browse in safe mode!! WHAT AM I MISSING??
