Unknown Network in my Finder
Hey community, here is my problem:
When I open my finder I saw that just now there popped up an unknown network called 'smith'.
I have seen the network coming up before, but never thought anything of it so never checked it.
Here is no network or Wifi other than my own near me, nor a printer device etc.
I do not have a lot of data on my macbook air itself, but I did have some issues with hackers in one of my e-mail accounts.
How can I block this?
Guest user box was never ticked anyway.
MacBook Air 13", macOS 10.14
