Is there a fully integrated browser / Email / messaging system?

I'm looking for an application that can do the following: MSN / Yahoo / ICQ messaging (Skype text messaging would be nice too), the POP3 email support and navigation. Importantly, All this has to be able to run through the HTTP proxy server as well, including downloads of Messenger and email .. There has to be free, but the trial would help .. Thanks ..
