Thanks to both of you - before I unistall my virus barrier, I would like to point out that I was several times in a hotel in US and my virus barrier informed me an IP address was trying to get into my computer.... So I blcoked it. This happened several times. What would happen if I do not have any virus barrier?
This is quite common in hotels as well as hotspots such as Starbucks. You should always turn your built-in firewall on when you are away from a trusted network such as your home or work networks. System Preferences->Security->Firewall tab->Allow only essential services. You should be protected at home by your router from all incoming attacks.
Little Snitch is an alternative to Virus Barrier, but only for outgoing traffic, not what you described above.
