Can you most more details on the message allegedly from Pacifist?
The demo version of the CharlesSoft software would run free...

older http://www.charlessoft.com/pacifist_olderversions.html
But, you would have to download it yourself. Could be some other
software is trying to spoof the Pacifist name to get you to load it.
Never seen the problem and I've used several versions of Pacifist.
And I get software from official sites and not softonic, etc.
Perhaps someone will post and offer lengthy advice that will show
you a list of things running in the computer, that may point to what
the item is you are seeing; and maybe offer to tell you its location.

Maybe you could see if the Etrecheck report may yield clues?
I don't use it, but it has helped in some cases to show system info.
Can't say as I've encountered the message you state about Pacifist.
There are several things about Time Machine and OS X recovery
that may be worth looking into; sorry to not be of much help here.
Good luck in this matter! 🙂
