@empressquartz How do you know it's literally a virus? 
As you said, the browser and your computer blocked access, so there's no way for you to know what comes after what was blocked, am I right?
There is a website in Brazil called ratondownload.org it is always blocked by my anti-virus and by the browser itself, but this happens because it was reported as a propagator of piracy, so technically, it is not every time that blocks appear that it is in fact a virus , the site I'm talking about offers several free software, but it is considered a threat... The ideal would be to try to see this app that downloads the mp3 with a virtual machine, then we could know if it is exactly a virus or not.
