|I boot to safe mode with command prompt. At a command prompt I type:|
net user administrator /active:yes
If it returns command completed successfully, then I restart the computer and when it comes up to the login screen I pick the now unhidden admin account, which in most cases is not blocked out like the normal account. If this gives me access, then I run combo fix, and malwarebytes to remove the virus, restart, log back in under normal user and run some scans to make sure I have got rid of it, then rehide the admin account. cmd to bring up a command prompt: net user administrator /active:no
To err is human but to really screw things up, you need a computer!
