It does say that the message would be removed after an hour. Hopefully, someone can lift this more early.
What did you mean that the results weren't clear? Do you mean that it has found some malicious files/code or it's hard to understand? You could probably put up the results here once you've gained access.
Just to lead on from what caftpx10, please can I suggest that you also take the following precautions.
- Ensure your Joomla installation and plugins are up-to-date. Currently, it appears you are running an out-of-date version of Joomla, and many recent updates include vital security fixes.
- Change your Joomla password.
- Change your x10Hosting account password, and the credentials for any additional FTP accounts.
- Ensure no other files have been compromised.
