Great, but you're computer-savvy. You know not to click the 9 phony "Download" buttons and to find the nondescript text that says "Download link (slow)", and you probably don't even end up on sites like that in the first place.
Nowadays, the first thing I do when "cleaning up" a non-tech friend/relative's computer is to install uBlock Origin. Since I started doing that, the number of repeat calls dropped precipitously. (To be honest, it's probably good for their fake news intake, too...)
The web is a lot scarier for most people than you might realize if you've been successfully navigating away from sketchy sites for 30 years.
