    It is not needed to reinstall windows defender as its an inbuilt mechanism in windows OS. You just need to enable it. Click Start > Settings > Update & Security. Now select Windows Defender, then turn Real-time protection on/off.

    It looks like others have answered your question. I thought this would be a good time to remind everyone to use Windows Defender in addition to (not in lieu of) a third-party anti-malware program. It tends to catch/block different things so it's good to have both.
