A few weeks ago, I had a malware problem, which I fixed.

Since then, whenever I want to shut down, my computer will not. I have to use the big blue button on the front of the CPU to shut it down for the night. The normal cycle does not function to do so.

Do I need to reload Windows to correct this, or is there another easier, faster way to diagnose and fix this problem?

Welcome to the forum!

This is one thing to try, but it's a bit of a pain- depending.

Go through your start-ups, one-by-one (at a time) and prevent it from loading when you boot. Once booted, shut down. If it still hangs, re-establish that program in the start-ups and move to the next.

The purpose is to rule out one running program possibly causing the shut-down hang.
