I have problems with RuneScape

When I play RuneScape I use Java now. It used to just say Run or Don't Run. But now since I got McAfee Securtiy I have to use Java now. And now that I use Java RuneScape goes super slow now and freezes continuesly. And everytime it says Loading Please Wait it freezes and says Connection Lost Attempting to Reestablish. It does this everytime and now I can't play RuneScape. Can someone help me?

Ditch windows.Short of that, find out what port it is trying to connect on and configure McAffee (however the hell you spell it) to allow connections on that port. Chances are there will be some sort of FAQ that explains this on the RuneScape site.
