fix website -- 3

my homepage stefanlanger.net cannot be accessed anymore. There is some re-routing malware, I suppose. So the task is to fix this issue via FTP access or Cpanel. The issue was fixed before, but re-appeared. So this needs a thorough fixing. Also some images did not display correctly before the issue - some text on the images need to be changed. This should be a quick and easy fix for someone with experience.
