> I'd get random garbage like a notification for some "grand prize giveaway"

???

how? what kind of malware did you install? have several W11 boxes, none exhibit this behavior. No "official" notification for a prize give away or any ads.

The malware is Windows 11 itself. It's an official Microsoft thing https://rewards.bing.com/sweepstakes/million/about You might not have seen it if the giveaway is not available in your region or if you are using an Enterprise/debloated version.
