On Demand (Manual) Scan Window

Whenever I downloaded a file, I've set up my download manager to automatically run a virus scan on the downloaded file. As a result, the NOD32 On Demand (Manual) Scan Window pops up whilst it does it's thing and reports back on anything found.

My question is, when the scan of the downloaded file has completed, the window then just sits there waiting for me to press the 'Quit' button to get rid of it. Is there a box I can tick or an option somewhere, where I can get the window to automatically closes itself without me having to press 'Quit' to get rid of it, if there was no infection found. (Obviously, I'd still want it to stay there if it found something in the file so I then don't open the file).

I can't find anything obvious in the options, so any prompts or advice would be appreciated.

Many thanks!
