@MeisterYoda: I found some sort of manual online to remove it from the registry.
So some things i removed manualy, after that I've run about 4 programs to remove malware, virusses, spyware etc.
I've tried shadow copy and panda decrypt, but nothing works.
There are no back ups to be found.
All of my drives, I have three hdd: C/D/E are infected. So I did not try to go back to an earlier periode through windows restore because of the files that I need are on D and E. (back up was off unfortanatly.)
