site hacked, fix please?

There does not seem to be much information on this robot hack so i thought i would put it out there if anyone experienced the same hack.

website title changed to:
[ Please do not post that code here again. It’s not safe. ]
Under Settings -> Reading:
swithced to utf-7. (fix: change to utf-8)

I have not seen any other issues so far. reset all passwords and tightening htaccess.
