Hi there, newbie here. I borrowed my mother-in-laws Dell laptop and told her I'd try and clean it up a bit. While trying to get rid of some bad stuff, I must have done something wrong, because now whenever I open up IE or Chrome i get the message "Proxy Server Not Responding." I have tried unchecking it from LAN settings in IE, tried resetting IE, ran malwarebytes and got a clean scan... I am truly stumped. I have no idea what to do. Note: I also ran sfc in CommandPrompt, everything came back ok. Please help?!
