It's understandable that many PC gamers want to get their hands on Grand Theft Auto V, since that's been the tradition for the console versions on the franchise to be released for the PCs some months afterwards. Also, many people are posting up how great the game is on social media, and video game news sites are talking about tips.
Still, it remains perplexing that many "unsuspecting" users are downloading the torrent versions of the game to their computers. According to WCCFTech, the torrent file, while looking legitimate (18GB of hard drive), is infected. The site did not specifically say how it was infected or how it infected other computers except that you're going to open up many windows with surveys in it.
Again, it's understandable that many PC gamers want to get their hands on Grand Theft Auto V, but please, do not on download any files, even if it does look "legit" because it can infect your computer in the worst possible ways. If Rockstar has not released the game for PC, then the file you're downloading is a scam. Make sure to check out its website for official news.
Also, don't use torrent files to download your games for the reasons mentioned. Instead, go to legit, reliable sites to pay, download, and play your PC games such as Steam, GameFly Digital, Origin, GamersGate, GOG, Gametap, and Amazon.
Use common sense here, and play your games safely.
