I have a suspicious file on my macbook. I tried to put it in the trash but that does not work. How can I remove this?

Hi sw1mg1rls,

Where is the file located on your Mac?

If it's a macOS-system-related file, macOS will prevent you from deleting it to ensure safety.

you could if you have the means boot from a different source.

Start your Mac is Safe Mode and try to delete the file.
