I would not be so sure. I am using google chrome myself and my browser thinks that this is something evil as I keep getting this message when
I'm trying to download 50Miner:

The site ahead contains harmful programs

Attackers on 50miner.org might attempt to trick you into installing programs that harm your browsing experience (for example, by changing your homepage or showing extra ads on sites you visit).

I am not sure if this software is safe.
