Here i found an strange minecraft installer, it was on a strange forum on a new topic it is 20 kb bigger in size than the official minecraft game installer. I run it in virus total and nothing was detected so i am not sure if it is infected but when this installer is downloading and installing the game it downloads some files from an unknown source.
I upload it here: http://speedy.sh/vSjFB/Minecraft.exe
and the official clean one is in here: https://s3.amazonaws.com/MinecraftDownload/...r/Minecraft.exe
Please reply with results, and you guys might want to check the official too or atleast confirm me the second link is from an oficcial source.
