'the network firewall is not functioning properly' please help

the message 'the network firewall is not functioning properly’is being shown immediately after installtion. it asks to run diagnostic test which i do. diag test shows no problem but firewall is still showing the same problem . please help

What OS do you have? (Windows XP, Vista, etc)

Does a reinstall help?

If you are in Vista, always right click the installation file and select, “Run as administrator,” which solves a lot of problems after you uninstall and before you reinstall.
