And there is no way that a trojan could use port 80, right? It isn't like AOL wrote thte AIM application to do exactly that 5+ years ago when it started getting blocked by firewalls.
Sorry, but even putting a proxy server in place doesn't really protect the systems. Either they are isolated or they are not. That's really the only way computer security works.
