Pop up message: "..." will damage your computer
I need help with this. I followed John Galt's instructions for an inexperienced user and have screen shots of the pop up message and the 3 folders he recommended I post. Now I'm looking for guidance on what to do. TY (I previously worked with an Apple Support person to get rid of a similar popup involving CrossSign, which I notice is still in a LaunchAgent folder.) I appreciate any guidance.
