It looks like some dubious characters are trying really hard to scam people out of their crypto currency by setting up fake websites that look identical to the real ones. There was one for myetherwallet.com (which has since been taken down) There also seems to be one for Jaxx.io (correct URL) The fake one is jqxx.io
Be very careful about which websites you are visiting and make sure they are the correct ones.
If you know of other ones then list them in the comments below to help make people aware of them.
