So I'm working on my parent's computers (they are BOTH afflicted with this problem). Only Skype and Teamviewer so far connect to the internet. My father can access facebook and google search (but none of the pages on google search) but nothing else. I'm not sure if these are cached versions of the pages or not. Other pages give the error: ERR: CONNECTION REFUSED. I have already unchecked proxy server under internet options in Internet Explorer. Even the antivirus program won't connect to the internet to update, and yet Skype and Teamviewer work with the internet. I have tried MalwareBytes Premium (removed several infected files) and Kaspersky (scan shows nothing). Please help. I will follow any instructions you give me. I have been working on this for 6+ hours.
