Hm... does coinurl actually contain malware, or is this an unethical business practice by google ? The ads sported by coinurl looks much like google adsense ads, but if Google is using their power to give warnings to all users on any site incorporating coinurl, that's really really bad, and evil.
I would think that could even be grounds for a lawsuit, if it's not really malware, but malicious blocking.
The site is now also blocked in firefox, with some more info here:

I don't know about this particular case, but I had a site that was listed like this wrongly about three years ago. I got google to lift the warning after some time, however even today, some of the major links to the site that gave it most of the traffic and value, never returned.
It is unfortunately not all that uncommon to use ad networks to try and insert malware though.
I really think google is getting way too much in the loop of things these days. I wish btc sites would stop putting them in for analytics and such all the time at least. For that matter I am tired of cloudflare backed sites.
