got this email from my hosting company....need someone to complete the work...
I've restored your site from our backups and run an audit on the account. It looks like you have two installations of Joomla [url removed, login to view], which are out of date and very susceptible to being hacked. I would recommend that you upgrade to Joomla [url removed, login to view], which is the most recent and most secure version of Joomla 1.5.x in order to prevent further hacks on your account.
Should be easy (it,s a very small website), but I don't have the time. Ho and I only think that there's only one instalation..but I'm not sure.
