Computer problems can be quite daunting - and believe it or not, they are not limited to Windows machines!
I don't even bat an eye when something happens. I just look for what might be wrong. Start googling. Run Malwarebytes. Cross fingers. Eventually a solution will emerge. Sometimes it just takes a little longer. I also am lucky in that I have a "back-up" computer that I can use if the main PC gets entangled in anything technical.
