I've started a SMF forum to learn more about hosting and PHP, MYSQL. But some how the site has been hacked... there was approx 2000 topics and 10000 + posts. The hackers have replced the index.php . My Server Host told me there are few other sites are whoch also have been hacked. They told me restoring only index.php will solve the problem. But at the moment I dont have the file.. How can I get index.php
Further if I wish to temporally stop the forum for a couple of month, what backup should I have to restart the forum... Only MySql data base will be enough or not...?
Thanks in advance
