And antivirus should not effect your ability to browse. You should try downloading a different browser than the one you are currently using and try that. If it works then we know that the browser itself is the problem If it doesn't work. Well then the problem probably is somewhere else.
Do you by any chance use IE7 right now? Have heard that some others are having problems using that browser with Limewire.
Pick 1...or 2,3 hmm you decide
