Hi, In my windows xp dos prompt, I enter the command netstat -na and found lots of lots of connections to foreign IP address's port 25. But I didn't open any mail sending program so far. In the Task Manager, I can't find the application whcih keeping sending the packet to the port 25. Please give me some advice. Thanks for help. Jason
Well; what IS that application? Any other details? Perhaps your computer has been zombied? Dunno. Pop`
