I was cleaning up my uncle's computer and noticed he didn't have a antivirus protector. I downloaded AVG and then after that the internet stopped working. It is giving me in Firefox and Explorer the same messages: "The Proxy Server is refusing connections" "Check the proxy setting to make sure they they are correct" and "Contact network administrator to make sure the proxy server is working" ATT came out yesterday all the equipment is fine. I have also removed AVG, gone into "Connections" LAN unchecked the proxy button, I have done the following as suggested from someone in the forum. Go to Start ... Run and type in cmd
A dos Window will appear
Type in the dos window: netsh winsock reset
Click on the enter key.

netsh interface ipv4 reset
netsh interface ipv6 reset
ipconfig /flushdnse the following also:
None of this worked. What else could I do to get this fixed?
