Well, thats basically it. Yesterday my notebook (dell inspirion 3542) had a update after turning it off, i went to sleep. Today, turning it on, all my letters became symbols. I don't know what to do. Is it the upgrade or a virus? Because i didn't donwload anything in a couple of weeks. I can't acess any system settings because they all became symbols. What do i do? The last image is what happens if i type windows button + R. I can't type anything because the window won't open.
