I have been given a harddisk of random games, music, films, and software, and I’m wondering how to go about having a look at it. As I understand it viruses can be hidden as all sorts of file, so how can hooking this HDD up to my computer infest my machine? Can playing a virus hidden as an MP3 file do it? Would it only infect me if it is set to combine with a certain media player, and I use that media player to open it? Will a scan with SAS, or Antivir (or both) suffice to check it? Will they scan compressed folders? I guess I’m looking for a introduction to the basics of how infections come about. Thanks for any help.
