I turned my computer on not long ago, and it said it was configuring an update as it does sometimes with those big updates, but the last update was one of those defender things a few days ago (i don't use defender, by the way). I am a little concerned about this, because it just seemed random... or did everybody get it? Windows 7, by the way. Actually, my little mistake. There was an update yesterday called Windows Update Agent and some numbers. Is this legit?
