Most firewalls require your "teaching" them what to allow and what not to allow, and also give you the option in the pop-up box to allow for just this one time, or to allow---or not---permanently. If you know the application and it seems legitimate that it needs internet access, then allow it. For example, if you open up Yahoo Messenger, and you get popups requesting access, then allow it. On the other hand, if you are not using an application and you suddenly get a popup, then deny it access out.
Whereof one cannot speak, thereof one should be silent.
