How can I fix the problems with the registry editor in windows vista?

My computer has been infected by a virus, and now I can't open the Windows Defender Security Center and Windows Firewall. I used Microsoft Security Essentials scan to remove the virus or virus. Now when I run a full scan it comes up clean, but I still have no firewall. I tried to fix this by using the registry editor. Once I got to the stage when I open the BFE (or any file) I get the message that the registry editor has stopped working. How can I fix it? I already tried the System File Checker, and he is unable to solve the problem. I also tried restore of the system several times without success.

Try to do the same thing in Mode without failure.

Steps to start safe mode.
