A general rule of the thumb is that if you do something on the computer and you get a popup request (like opening Firefox), if you recognise the application than allow it. If you are not performing an activity and get the popup request, or do not recognise the program originating the packet(click on Detail if needed), then click on No, but do not make the decision permanent; if something untoward happens as a result of the decision (you cannot lauch an application, for example) you can thereafter allow it.
A handy way to begin using Sygate is to use the APPLICATIONS icon to see all the applications you have and make an initial decision for each one
Allow, Block, or Ask are the choices. You can allow your AV and ISP connexions,,block Realmedia update, and ask for other applications that you might not want to automatically allow Net access: IM applications and media players, for example.
A third example of popup request results in an application change. If you have updated software recently, then allow it; if you have NOT knowlingly updated a particular application, program, or game, then check NO; if this subsequently prevents it from running, then you can allow it at that time.
Hope this helps,
