I've since returned the laptop to the person I was helping.... The errors/files vary. They seem to typically be in the 'programs(x86)' directory (which is probably one of the largest folders). There are typically 5-10 errors on a complete system scan, and the folders are somewhat constant, and the reported files are also somewhat constant, but as I said, scanning just that file works fine.
I should have access to the laptop in a week. I can post the complete report then.
