This is a good one. We get standard phishing tests which make no sense. It is usually a person I don’t know, from a company I haven’t heard of asking me to edit/review a file they share. People who design these tests should know that people do NOT jump into the opportunity of editing/reviewing files or receiving tasks. I imagine real phishing attacks must be smarter than this.
But have you tried restarting your computer and reinstalling all drivers?
