No internet browsers are working

hi everybody i have firefox internet explorer and opera and non of them are working, on firefox its says connection refused so im using the internet browser on limewire can any1 help me get firefox working again

 

what is not working, are they just not connecting to the internet? so firefox and opera don't work, but what about IE?

considering you mentioned you use limewire, there's a good chance you might have a virus floating around.

Using another computer, download AVG Free (a good free antivirus app). Install it on your infected computer, run the updates, and run a scan on your C drive to see if it finds anything.
