Unfortunately, there are folks like that in this world! Too bad they do not adhere to the very applicable quote from the movie "The Day of the Jackal", where Sidney Poitier says to Richard Gere: "Go along, and we'll get along".
In any event, I suspect you are still having the issue. With that in mind, maybe you need to completely Erase and Format your internal drive, do a clean, fresh, "virgin" installation of whatever Mac OS you want (or are using), and then, via Migration Assistant, "migrate"/copy needed stuff from your Time Machine backup. Again, though, I am unsure as t which backup to use, to insure that it is a "clean" one that does not contain any pieces related to your issue.
However, there is, potentially, a more serious issue. I saw this yesterday on the site
www.macworld.com, and also on
www.yahoo.com:

I don't use iCloud, not even for backups, so this will not affect me. I also don't know how credible it is, but given all the sources reporting it, it could be real. So maybe you might want to "suspend" using iCloud.
