(I just got hit at an HD Wallpaper site but I don't know which one, using Palemoon browser) Defender caught it before it could do its dirty work!

I just got hit with this - Trojan:HTML/Brocoiner!rfn

This JavaScript code is a cryptocurrency miner that has been found on both malicious and compromised websites, including sites that offer streaming videos, adult content, and online shopping.
When this JavaScript is loaded—whenever one opens a webpage containing it—it automatically starts to mine for Monero or other cryptocurrency. This mining activity, often initiated without user consent, consumes resources and can slow down affected PCs.

PaleMoon and Firefox have just released updates: https://www.us-cert.gov/ncas/current-activity/2018/09/05/Mozilla-Releases-Security-Updates-Firefox

There are hundreds if not thousands or even millions of sites using coin miner scripts to get money and use your cpu to do it.

Unfortunately the only protection is an AV and defender is better than many others at detecting these website scripts.

Defender is what I use and performed as you describe, plus I do manual scans with Malwarebytes Antimalware (MBAM free) and SuperAntiSpyware (SAS free)
