Bitdefender Scans 1 File But Detects 2 Items !?

Hi,


I have been asked to downlowd this file :

I don't know if this file is safe or not.


It is supposed to be (and probably is) a .png file


The strange thing is that : when I download it and scan it with Bitdefender Total Security 2016 just after downloading it, it says it's safe, but it detected 2 items.


When I scan it again a few seconds later, now it only detects 1 item.


So my questions :


Can there be 2 items in a .png file?


Why is there just 1 item a few second after the 1st scan which detected 2 items?
