coinhive.com is not a virus site, it has a javascript running that has your computer mine for coins to help pay for the website. I believe they were running a test earlier but I haven't seen it on this site as of yet and I've been on daily. It's on 3dzone.link and I navigate the site well with it running. The false adblocker that pops up as I do not run any ad blockers, I have a host file that blocks spammers and I make exceptions to like ad.fly but I do not run an adblocker so I disable it with noscript. Noscript will disable coinhive as well, it's an extension in Firefox however you may not be able to download unless you enable for the download.
