Tell me some good free alternatives to msn?

[Steve]

MSN is shutting down on March 15 and I was looking for good free alternatives so please share with me what you are going to use after MS discontinues MSN.
MS recommends Skype but there are too much security issues with Skype - viruses, wiretapping ... . Is there something more secure ? Something more enterprise-oriented ?
Thanks for your help guys but I found Brosix which I think it is the best instant messenger for Business. It has most of the features that I need in my day-to-day business life.

Special thanks to Gabriel G and Naomi - I will definitely try the QQ chat !

Why don't you try QQ International? It has the largest userbase in the world after Facebook, too bad it's not that well known in the West. It's great, with all the features of a great messenger and solid chat rooms plus videocalls. Moreover it has a live translation service (100% free of charge!) to instantly turn your chat messages to any language you want.. it's a bless, especially if you have to work or be in contact with people from far away. Give it a try, there's also a Facebook version (QQChat) which works a treat.
