Still seeing on forums like the Microsoft Community, volunteer moderators and other supposed authorities stating Defender (assumed out-of-box) is "all you need." Maybe but this assumes all users share the same blah online behaviors. Either that or they talk out of both sides of the mouth.
Microsoft got a one-star rating this time. I sense a small gold rush toward the numero unos--ESET, GData, etc, as usual.
Comparatives, I use for entertainment purposes. But they consistently show MS is all over the place from one quarter to the next. I mitigate the fluctuations with first and third party tools. It's like taking a daily vitamin tablet.
