When you removed Norton Antivirus, did you use the Norton Removal Tool? How did you configure Zonelabs? Do you have the security level set on high? If so, see if the two browsers are still locked out at medium.
Did you try going back to a restore point preceding this problem? This should tell you if it's related to one of the pieces of software you mentioned - Nortons and/or Zone Labs - or if it's a different problem altogether.
If you've never used System Restore, go to Start / All Programs / Accessories / System Tools / System Restore
check the box to Restore my computer to an earlier time and click on Next. You'll see a calendar with highlighted dates. Choose one of the dates just preceeding these problems and allow your system to return to that date. See if the problem goes away.
After you see if restoring to an earlier point preceding the installation of Zone Labs changes things or if you still have the problem, you will have more information to work with. If Zone Labs is the problem and restoring to an earlier restore point does help, you can temporarily turn on your Windows Firewall as an option until you can figure out what the problem is with Zone Labs. It can be turned on by going to Start / Control Panel / Windows Firewall.
