Hello, I have a laptop here that for some reason is sending out billions sometimes even trillions of packets it just keeps rising! I have reinstalled the NIC driver and tried a different NIC but the same thing keeps happening! I have also renewed the IP, flushed DNS, reinstalled the network stack, I really can't think of anything else to try. Anyone have any ideas?

Thanks. We'll let you know when a new response is added.

I would think it is not your nic but your laptop. Do you have Ad-Aware installed?

    I'm inclined to agree with derlenbusch. You've probably got either spyware or viruses. In addition to AdAware, I'd also recommend Spybot Search & Destroy, and then get McAfee's Stinger utility from http://vil.mcafee.com/vil/stinger. Bob

    I agree with the others. One way to get a good idea as to what is running on your computer and a good way to allow others to help you is by using one of the freeware programs that will display all the processes and relate them to the registry. I use one called HiJackThis as it allows you to create a text file that can be published. http://www.spychecker.com/program/hijackthis.html If you would like I am sure any one here would be happy to look at the file and help you determine what needs to be running and what is malware and where all the packets are intiating from.

    How bout trace the connection, close all programs, do the netstat -ano (if our OS is XPPro). From there you can see which connection is established, then check the PID, what program(s) they are. it's probably spyware.. but maybe "something" else gd luck..

    Sorry it took so long to check out the HiJack log, I had a email server go south at a client. The log looks OK, so in most cases that rules out Malware. I was curious and require your patience on this. But I would like to know how you are determining where the packet flood is coming from and whether that computer is facing the Internet or always behind some security device. If it is not malware, it might be owned and acting as zombie/repeater. Please remember that it would only take one instance of non secure connection to get owned, especially if the computer is not up to date. The next steps to resolve this will depend on yout thoughts are.
