or, sorry. I've seen that I must answer the question first or tell my opinion. I think that there is no matter where you downloads but you must remember about protecting your computer and data with the help of antivirus software and you can read more about this importance on numerous resources. In any case, you should better choose the official website, and the risk of getting some viruses zero is equal to zero but there are chances when people infected their PCs after downloading official software and to be honest, it is hard to explain. emulator-zone.com is also a trusted website. I think you can use it without any worries and if something wrong you can always write on this forum.
