Read the comments since its a keygen, like all other keygens your anti-virus might say it has a virus on it, but it doesn't you just have to disable after downloading the the program open > get key > virus scan if you are skeptical and you got yourself a full ******** version.

EDIT: Make sure you have a program like UTorrent to open the files.
