Default DNS changer virus - fail to update antivirus or windows updates

Hello,
I got infected on 20 April ( last auto-update date from Bitdefender IS 2009) with something really nasty ! What does:
- doesn't let me access any known antivirus WEB sites
- block updates of Bitdefender and your tools ( I had to update them manually )
- Windowsupdate redirected to fake Google page

Bitdefender complain a lot about infections with Trojan.Heur.VB.xxxxxx ( some random numbers ). Even scan with BD in Safe Mode didn't resolved anything !

Some details related to logs:
- SuperAntySpayware run for several hours and reported some infections, most of them cleaned
- after that I run BD in Safe Mode, over the night and removed some other infections ( log not attached here )
- then MAMB ! After installation, I couldn't run because BD was moving mbam.exe to quarantine ( infected with Trojan.Heur.VB.xxxxx). I had to install it on my notebook, rename the mbam.exe to mbam.bat, copy on CD-RW , copy on installation directory from infected PC and start it. Run first time, removed some infections, reboot then run again
- Combofix - couldn't run, with BD antivirus disabled . I had same approach - renamed to Combofix.bat and start. After small loading bar progress, BD just pop-up ( still disabled !! ) and after short time an error window pop-up ( see attached image )
- MGtool - see log - I had to disable BD to allow running

I hope you can give me a hint here !
Thanks !
