Hi, kaylalee888. Welcome to LandzDown Forum.
Is your computer a desktop or laptop and do you have an external keyboard and another mouse you can try using to see if they work? If you are unable to maneuver on the computer it will prove difficult for you to perform the tasks we would need for you to do in order tackle any infection on your computer.
That said, a member of the security community has compiled excellent instructions to save some files/folders before either reloading the OS or purchasing a new computer when dealing with a machine with a corrupt OS.
Please let us know if a different keyboard/mouse help the situation or if you would like assistance attempting to save the files on your computer before your husband formats it.
