Hi, if a file (such as a picture, music, video, document, etc.) is infected, and it's uploaded to a email account or cloud service like Google Drive, OneDrive or the likes, can it infect other files that are already in that account or particular folder?
P.S. I'm wondering how it's possible for a document or media file to be infected anyway (as t's not a DLL or Executable), is it possible for such a file to have secret malware/spyware/virus/whatever in it somehow?
Thank you in advance!
