Yes if you have time to preform them. I would Update Windows first.

I would change the order somewhat:---

Install pending Windows critical updates.
Install any application updates.
Run your resident anti-malware scans.
Run one on-line scan (you can vary which one each time)
Perform any file maintenance (deletions in particular) as well as disk cleanup.
Run checkdisk and then defrag. This should be your final step.
