I gave a lecture the other day in powerpoint and the projector required me to plug into the system using the blue socket at the back (parallel port?). I am convinced they downloaded my whole disk whilst i was talking. Would Zonalarm have spotted something like this and given an alert? Or can they just do this easily?

    Is your name Paranoid Android? Yes, data can be transmitted via the parallel port. However, it it is connected to a projector it would be connected to the VGA port (usually blue on most PC's). This is video only and not accessable into your system.

    Even if it was connected to the parallel port, ZoneAlarm would pick up an outside program that it did not recognise accessing data... but only if it is configured correctly. Hard to say from here.

    Basically, it sounds like you connected a projector to your external VGA port to display something on the big large white screen. No access to your hard disk would have occurred.

    Hope this helps

    Dear Barny,
    yes, probably my name is Paranoid Android, but as Gates used to say, "Only paranoid survive"! Anyway you have put my mind pretty much at rest. They did indeed plug into the blue port at the back and the screen did display the powerpoint during the lecture. So this port doesn't have access to the computer harddisk after all. I have Zone alarm configured in a pretty standard way and I didn't get any untoward message during the lecture. So I imagine there is no problem? Just one last Yes, will do.
