You can try Avira rescue cd. You may need another pc to download.When you download the file,double click on it,you will be prompted to insert a cd,the program will be burnt to disc.Inset the disc into " infected  " machine and reboot.This program is fully updated and does not load windows.
Your problem may well be elsewhere and not virus related at all

Why are you sure you have viruses, Germa?
What operating system is it, and what other security applications are installed?
What AV was installed before Avast?
