Automatic creation of a desktop shortcut for Acrobat Reader ?!

Hello everyone !

I don't understand what's going on... I was on my computer in the middle of the night, when suddenly, when I looked at my desktop, there was a shortcut to Acrobat that had just been created a few minutes ago (I check the shortcut properties to see the time of file creation) !

However, after my checks, no software update has been made since September 29...

Have you ever had a desktop shortcut appear like this?

I specify that it points well towards the original software.

Thanks for reading me !
