PROBLEM SOLVED. I choose a simple route of solving this by watching and videoing the Scan Progress: It spent a lot of time then blue-screened when checking the file: C:\programdata\Playrix Entertainment\Fishdom2\Storage.xml.bak I assumed I could safely delete this backup file so i did, and emptied my recycle bin. When I scanned again, mbar 1016 ran to the end. I must say that simultaneously with deleting this file, MBAR 1011 prompted me to install the latest version, which had jumped from 1011 to 1016. I didn't think my version was that old. It's hard to tell, but either deleting that stalled file, or the new version of mbar, allowed mbar to run to the end - clean. So Good News. Case closed.
