Get computer is updating everytime I shut down computer

I don't know if this is malware or so something gone wrong but everytime I shut down the computer I get a message that my computer is installing an update. Often it is installing two updates and it takes at a while to shut down; which is a problem late at night when I am waiting to go to bed.
Even when I have not been connected to this internet while using the computer I get the same message with some hard drive activity.
I have tried to turn off the auto update option but I still get this message.

Anyhelp in stopping this would be very welcome thanks.
