Recently, I ran a full scan of my computer using Defender and the system reported a trojan malware on my computer. The threat was quarantined.  Question I have is why did not system not detect the trojan when it was downloaded in the first place? How confident can I be that Defender will protect my system. Here is the message I got:

Is there a setting that I can enable to make sure this doesnot happen in the future? I have default settings now. Having used Microsoft365 from BPOS days in the year 2009, I am pretty confident about capabilities of the Defender. This, now has me worried. Should I install McAfee or Norton in addition to Defender?  Thanks
