It sounds like your system has a program "Listening" on port 1080 or a like port which is commonly used to traffic anonymous IRC connections. This is typical behaviour of machines that have been exploited via Trojan Horse virus or insecure settings.
Take measures to secure your machine and clean it of viruses. Purchase at least 2 virus scanners, a decent firewall, and keep up on your Windows Updates.
And NEVER EVER click on a link that someone gives you on IRC. Even if it's a hot naked girl showing you her pic. That pic is really a nasty STD. (note, there are no hot naked girls on irc)
Well. At least I won lunch.
Good philosophy, see good in bad, I like!
