How come my compuer is slower than normal after having an issue running an update?

Q: My computer has been running slower than usual. I usually do a disk clean up every time I finish using my computer. But even with doing so lately my computer still runs slow. I also noticed that when I come to shut down the computer, the blue windows backdrop will appear with a message similar to this ” preparing to install udates1 of 1, do not turn off computer, it will shut down automatically”. So I did as the message asked me to do, but the computer never shuts down. Should I be concerned? Does my computer have a virus?
