It does the scan OK, but then the window disappears too quickly. So I can’t read it. I am happy that it disappears automatically but need for it to remain on the screen for a few seconds so I can read it! 
If it disappears, it means that no virus was found (when a virus is found, the virus dialog pops up).
If you want to show the results even when no virus is found, you can turn on the corresponding option on the first page of program settings.
I’m afraid no “delayed” display is currently available.
