I have a Nexus 7 Android tablet.
When I connect to my WiFi at home it keeps automatically adding a proxy on
localhost:3128 to the connection. When I remove the proxy it works for a few hours and then I see the proxy is back.
I removed the WiFi connection and set it up again and I still experience this issue. I don't experience anything similar on my other devices like my Android phone.
Does anyone know how I can figure out what is causing this or how I can fix it (I don't want to do a factory reset)?
