Proxy server (malware)

I can’t connect to the internet it keeps saying the about the “proxy server” and the thing say automatically detect settings ( windows 8) It keeps turning on I already did the full system scan with N. 360 and it get rids off/ resolve the virus, “I think?” And it still won’t allow me to use the internet even tho my connection is on I don’t know what else to do with it, If there’s someone who knows about this I really appreciate it.
