NOTE: I just tested 1 link, and if you refresh the same page couple of times you may NOT get the warning anymore because it's a related to some ADS that are circulating through all Zippyshare servers. Other links may work fine! Here are the results:

So as you see, some of the site's servers have definitely been infected with some kind of phishing script. The culprit is the ADS, Someone is running those scripts through an ad campaign. The way to find out exactly who is a bit complicated. I've contacted Zippyshare (u should do it too to press them into fixing it sooner) and they will hopefully block the ad campaign in question!
You can always click "Ignore the warning" to "continue" to download, I do it all the times, but you must have a good antivirus just in case. Otherwise, let me know if you need some other download mirror for the game you want.
