WP-admin inaccessible

Hello forumers. I have a huge problem.

I haven’t entered my website for 2 days, and just today I tried to enter. To my surprise, when I try to go to the /wp-admin, the browser (in different computers) shows an error message.

Firefox can’t establish connection with server in 127.0.0.1.

Don’t know what to do.

I also realized that today my website got more than 400 views, when the average goes within 50-150 (when I post something).

Somebody knows what can I do? Thanks ! (Could be a virus from my computer who’s stealing passwords or something?)
