DNSChangerRemovalTool.dmg

Hey all, I was checking out a post about someone's accounts being hacked. My cursor went over a link (I didn't click on it) and it downloaded"DNSChangerRemovalTool.dmg". ***? How do I get rid of this thing? I didn't give my Mac permission do to this. Now I'm afraid my s**t's going to get hacked. I went to finder and moved it to trash. Will that get rid of it or is there something else I need to do?

It's not going to do anything unless you open it.

Here is what it will do when opened.
