Another stupid victim here, my whole Jaxx wallet was emptied (it was a lot..not only BTC) about 1 day after I used http://mybtgwallet.com.
I can give all the details if it's of any use.

Because it was referenced on the official http://bitcoingold.org/ site, I assumed it was safe and checked by the devs.
They now removed the link from their site and also at the bottom of their page it now says they are not responsible for third parties, bla, bla.

At http://mybtgwallet.com it now states 'Access to the site direct from your browser, dont search in google or access from any other website. It’s reported that some hackers are disguising the real wallet. We are investigating the problem.'
Also the github is updated.

What to do now??
