Recommended Actions —

_Option 1: Move Internet Zone slider to Medium _

  1. Navigate to the "ZoneAlarm Firewall" panel
  2. Click on the "Overview" tab
  3. Move the "Internet Zone" slider to medium

_Option 2: Uninstall the hotfix _

  1. Click the "Start Menu"
  2. Click "Control Panel", or click "Settings" then "Control Panel"
  3. Click on "Add or Remove Programs"
  4. On the top of the add/remove programs dialog box, you should see a
     checkbox that says "show updates". Select this checkbox
  5. Scroll down until you see "Security update for Windows (KB951748)"
  6. Click "Remove" to uninstall the hotfix

_Option 3 (advanced technical skills required): Add your DNS servers to trusted zone _

  1.  From the "Overview" panel, select the "Firewall" panel then click
     on the "Zones" tab
  2. Click "Add", then select "IP address" from the shortcut menu. The
     Add IP Address dialog appears. Select "trusted" from the Zone
     drop-down list
  3. Type the IP address and a description in the boxes provided, then
     click "OK"
  4. If you are not sure what IP addresses to add:
        1. Click the Start Menu
        2. Click on Run. Type "cmd.exe"
        3. In the command prompt type: "ipconfig /all". Look for DNS
           Server(s) in the output of the command
        4. For each IP address listed, navigate to the "Zones" panel of
           the "Firewall" tab, add the IP address, select "Trusted
           Zone", and press "Apply"
        5. After you are done adding DNS servers click the "Apply" button

I think I'll wait a bit for a more permanent solution.

The latest version of Windows Update is incompatible with Zone Alarm, causing the firewall to block access to the Internet via IE and/or Firefox. Zone Alarm is working on a solution, but in the meantime, I've shutdown ZA and gone back to Windows firewall until they can get along.
