I don't think you can get more data about the shield from that window (unless it's one of the last five files that are shown there).
You can modify the parameters of the report file for the particular shield - and let everything (even "OK files") be written there. Afterwards, you can inspect the report file and see what was scanned; however, it's more a troubleshooting option than something you would want to have enabled all the time (the report file may grow quickly in size with that settings, and the amount of disk activity grows because of the additional writes to the report file).
