Okay, I've got my son's computer where he allowed his anti-virus software to lapse. Grrrr. He has lots of college schoolwork that he can no longer access.

I've run the Dr. Web decryptor but it was unable to find main key and only part of files could be decrypted. Where are these decrypted files stored sincd I was unable to find not a one. Tried the sourceforge suggestion which I downloaded on a thumb drive to my computer (his Internet is not working), opened up on his and got an error msg. "This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem."

Is this because the HKLM\Software\Fcd registry entry is absent? With regedit where do I go to see if this registry key is there?

Thanks for your help as I am about to pull all my hair out.
