When my Norton360 ran out I installed Microsoft Security Essentials but since then I've been unable to get onto the internet.

The message I get is:-

THE PROXY SERVER ISN'T RESPONDING.

CHECK PROXY SETTINGS 127.0.0.1:58226 FROM CHARMS, GO TO CHANGE PC SETTINGS>NETWORK>PROXY.

MAKE SURE FIREWALL SETTINGSAREN'T BLOCKING YOUR WEB ACCESS.

I've tried to follow the directions but nothing is being fixed as it stays as it is.

Please help as I'm not sure exactly what to do.
