I' not only new to the Forum, I'm new to Computers. I have done a scan from Gibsons page and it indicates that my FTP Port 21 is open. None of the others are. I don't know what service to block to stop this. I don't have a FTP program installed on this PC. My Machine is Host, networked by crossover with the wife. I have the free edition of Zone Alarm, just updated. Running Win XP Home on both machines.
