I do not know what this is.

Reproduction Steps

  • I have downloaded Bukkit I think.
  • Then I have downloaded some plugins
  • Additionally, I also added my own downloaded plugin (non virus, just a premium plugin)

Make sure you have the right server type selected and that you hit (download/update)
