Hey @t-p ,
Thank you very much for your quick answer.
These news are very frustrating. Since we’re not making any profit with our Podcast, it makes no sense for us to pay a huge amount of money for a cleanup-service.
It seems that what we have to do is completely clear up our server via FTP and then rebuild our website form scratch and memory. The idiot that I am has also never made a backup of the website.
Thank you for your help anyway, at least we now know what happened.
