I recommend you download a known good Windows 10 ISO directly from Microsoft and start over with a clean wipe and install from that ISO. Windows 10 does include its own anti-malware program called Windows Defender. More importantly, given the presence of one non-Microsoft "bundled" app like this, I would consider the entire system to be possibly corrupted and hiding unknown malware. This false positive on System Update is certainly a good reason to doubt its quality. Apparently it used to be considered a virus/malware itself, but more recent reports say that it is now probably legitimate but not very good.

Where did you get your Windows 10 installer image? ByteFence is not something that comes bundled with Windows 10.
