Windows Update shows that my PC needs Windows defender (Definition Update for
Windows Defender - KB915597 (Definition 1.20.2825.10)). I am worried that
installing this program may bring down the speed. Is this really needed?
 
If WU tells you that you need a definitions update, then I'd assume the
application is already installed. The definitions update certainly won't
cause any change in performance.
