Looking for suggestions on a free firewall. I was using Zone Alarm and installed the update to version 7. I did not like the toolbar and email scanning feature. I uninstalled Zone Alarm version 7 and now I can't reinstall the older version or the newer one now. I have run through regedit to clean all references to Zone labs & zone alarm from the registry and still can't reinstall either version. Now looking for an alternative. Suggestions appreciated.
