I was opening a document on my computer and double tapped the file below it; A (more than probable, malicious) Skype.dmg file, likely downloaded from a popup. Normally, when I see them I send them straight to trash.
However I made the mistake of double clicking the downloaded skype.dmg file and am unsure as to whether this means it has done any damage.
(Im using Avast security as an example of what I saw on my screen when I pressed on the Skype.dmg file)
When I double clicked the skype.dmg file, an installer window opened up, however I did not click install, instead I closed the window and removed the program to trash.
However, I then noticed in my Finder window that the file was still there in the devices tab:
I then ejected the program, and deleted the icon on my home screen:
This question, although similar, differs to another question on this forum (Are auto-downloaded malicious .dmg app files a security risk if they are never opened?) by the fact that I have double clicked the file; Opening what may be an interim facade (picture 1) between installation and execution, although I'm not really sure.
Even though I clicked it, have I installed the Skype file?
