Yahoo messanger alternative

Today, I was wondering some desktop application that I can use for yahoo messenger. I know some apps like tweetdeck and so much more apps for facebook and twitter, but I don't know anything that I can use for chating like yahoo messenger.

When I type Yahoo messanger alternative, I found some forum post that suggest me some apps that told useful for chating by yahoo. The first is ebuddy, hmmm... not a great tool, because that is a mobile apps. So I search again with a different keyword, "lite yahoo messenger", but that's not the best, I still see something from yahoo.com.Until I saw a forum post, very old forum I think, because it containt some messenger apps that we don't use anymore. It don't event say anything like facebook or tweeter, what an old apps I think. So, the app named Miranda. Like a person name right?

Miranda is a lite app, so you still can connected even though you have a slow internet connection. And I think it is free from viruses. Because sometime, my yahoo messenger sending message automatically. That makes me feel so anoying. My friends blame me because when they click the link that sent automatically by my yahoo messager, their yahoo messaenger also sending auto message to all my friend's friend. So, what do you think? It is a great yahoo messenger alternative right?
