I lived with another person while I was attending school online. I was using his WiFi for phone and computer. When I left, all my passwords were changed, my settings, everything that could possibly be changed has been. My photos deleted, eventually my Chromebook has been totally disabled, will not even turn on.
I've received an email from Google saying my email and password was used to log in from Moscow, but was stopped. Is there any way to prove this was done? What can I do to stop it?
