Trouble is that this computer did not have any P2P software installed.
Norton was running in the tray and had the latest updates !!!
I have used P2P software plenty of times with my Etrust antivirus, KPF, Spywareguard and spywareblaster and never had any problems. Etrust will even alarm if I look at a web page that has infected attachements ect..
Norton Internet Security is a total pile of steaming useless rubbish !
P.S. From now on I am going to call the programs " naughty bugs " to save having my spelling picked on
