Localhost connected to Localhost

[nefar]

Recently I've noticed Localhost being connect to Localhost on strange ports 1 digit apart.

XP console netstat segment:

Active Connections

Proto Local Address Foreign Address State
TCP Athlon:4564 localhost:4565 ESTABLISHED
TCP Athlon:4565 localhost:4564 ESTABLISHED

This seems odd to me... It just started happening recently and it seems to stay connected even on a fresh bootup. I use Mozilla Firefox for my internet surfing, have anti-virus software and I run Ad-aware regularly so I've kind of ruled out ad/spyware.. Anyone have an idea?

Thanks

Use the command netstat -o to see which process ID has the ports open, and then use the command tasklist to find out which application is associated with that process ID.

These appear to me as pretty normal Netbios announcements. I do not see a virus or other malware issue.

It appears to be Firefox.... The ports are never the same... They always change.. I guess this is normal? Thanks for all your help.
