SOS URGENT website not available

Hi

I had installed AVH 1st defense and it worked for a month. But as of today NOBODY has access to the website even if i delete all the files (at the network level) !!!!!!!

Here is the message I get:

Access has been blocked.

Your IP [188.165.248.134] has been identified as spam

Protected by: AVH First Defense Against Spam – WPMU DEV Version

Please help. I do not understand why I still get the message after deleting the plugins from the server!

The server is http://roxanajones.com

The admin is http://roxanajones.com/wp-admin

ID: admin

PWD: dsc4Pq4!

Thanks a lot for any help.
