Malware - several types and no safe mode boot available

There are several types of malware and the "Windows Safe Mode" boot is no longer working (automatic reboot never reaching the loging screen). Several malware seamed to be cleaned with DrWeb, Karspersky and AVZ, but there are still some remaining. One of them is being executed through rundll32.exe with dll files such as wvvvur.dll, khiiji.dll, and others (it seams all the time it creates new files). Tried to stop it with process explorer, to disable it through msconfig and to fix it with hijackthis but it will starts by its own all the time again...
