"GTA 5 Full PC Game + Crack" scam is 18GB of nonsense
GTA 5 has not been confirmed for PC, and the possible future port has not - repeat, not - been leaked to torrent sites. The 18GB "GTA 5 Full PC Game + Crack" package doing the rounds merely sends the user to a scam site and attempts to rip them off; it's quite probable the files in the pack are fraught with viruses and other nasties, too. According to WCCF Tech, "thousands" of hopeful gamers have downloaded the file already. Don't join them.
Thanks, PlayerAttack.
