I have a HP laptop that was not used for 3 months. I cranked up the laptop and began using the Explorer and everything worked great. I than updated Windows with several updates and my browsers stopped working. The computer shows that it's connected to the internet through my wireless router but no browser will find a website. I also tried to connect through a network cable to the router and still the browsers would not connect to any websites. I tried to go back to a restore point from several months ago but that made things worse, several files could not be found on start up. Original error message said the system could not find a proxy server for the connection.
System: Windows 7
Browsers: Explorer 9 and Chrome
