My Win 7 laptop used to run through the usual boot process and then prompt for log in with the windows wallpaper as per a million machines out there. But there was a virus that needed cleaning up and after that, I now get a small blue password prompt as soon as I switch the laptop on. It accepts my Win logon password and then boots through. But then it takes me straight to the desktop without any further/usual logon prompts. Anyone know how this is happening and how I can resore this back to normal, removing the initial prompt and having the usual pre-desktop password prompt back?
