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.

Reboot your system to complete the process.

If needed : type these one line at a time, press enter after each line. See if it works after each.
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?

Hi :welcome: to BleepingComputer,

 

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..

 

If you check the proxy button now is it on again?

 

Can you execute the following if you have another computer to download the file?

 

Download MiniToolBox and save the file to the Desktop.
Close the browser and run the tool, check the following options:

  • Flush DNS
  • Report IE Proxy Settings
  • Reset IE Proxy Settings
  • Report FF Proxy Settings
  • Reset FF Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List Winsock Entries
  • List last 10 Event Viewer log
  • List Installed Programs
  • List Devices (select Only Problems)
  • List Users, Partitions and Memory size
  • List Restore Points

Click on Go.

Post the resulting log in your next reply.
