The issue is, the HELP_RESTORE text files showed several different owners, so it's hard to tell if all these people got infected at the same time, or if it came from one spot and then spread out to others.
I was told by another person once that all you need to do to find the source of the infection is check the owner of the HELP_RESTORE text file. Well, I checked and found at least nine or ten different owners when I checked a few of those files.
