If I had known that you are hosted at eleven2, I could have explained in more detail

that hacking happened at many hosters, at my side there were kurdish hackers.

There is one very fast help at your side:
reload ALL index-files to your webspace again

all index-files (index.htm, index.html, index.shtml, index.php, index.cgi) whichever you have
because they overwrote all these files

remember that you have a lot of these files, I forgot one or two of them the first time

I also asked the hoster of the files which are linked in these hacked pages (video, sound etc.) to delete that account

when I did a websearch for the text which was placed on my page, I found more than 500 affected pages...

please take note that they did not exploit a weakness of Pixelpost, they just overwrote "our" index.php

these idiots are just fools which are clever enough to find security holes and exploit them but not clever enough to fight for a better life with peace and without war
