      I was asked to remove some viruses and spyware froma friends computer, and after the majority of them were removed I installed a program called spyware doctor as it was advised to me to be good, since then i keep getting a blue screen about two minutes of entering the password, and i can use everything on the computer till then but then it shuts down into a blue screen with this fatal error message, what can i do?? also i keep getting a netdc.exe error, but cant do enough to get rid of it!! please any advice would be great,

thanks,
