How do I delete these files and are they hazardous?
So last fall my programmer cousin had physical access to my cpu and installed some bad stuff, one of which was a program that automatically sent a backup of my entire laptop to his Dropbox account every time I logged in. I’ve been hounding through my files for a while and while I think I’ve removed everything, I’m no IT pro and I only did the best I could with the help of YouTube and the internet.
Recently I’ve been trying to clean up a bit more on my MacBook, and when I went to erase some files I wasn’t allowed to erase any of these. So my question to you, is this “datadetectors” file a problem? It says I “do not have permission to access or view its contents” and therefore I cannot delete it. Is there any other way to get rid of this, and are any of the other files in the photo a risk to my laptop or online safety? What is the best way for me to go through my Mac and clean this junk out?
TIA
