My PC IP is sending out information to other random IP Adresses (Router Log)

Hi, I recently checked my router log and am getting many messages of connections to random IP addresses around the globe. I recently reinstalled XP on my system but this may have been happening before that as well. Can anyone help me to figure out why this is happening? My router showed no such information before when I have gone to the admin console.

Thanks
