It does appear to have stopped its deluge about a week ago. "Coincedentally", I used Link2SD to move some apps around at about that time.
My greatest concern is to find out if this *is* a concern, if these apps could be malware.
I've done several searches and am shocked that I can't find any other answer, so here I am. I can't begin to guess where to start looking for this solution.
Thanks for any help available!
