tutaudio.ru é seguro?

tutaudio.ru came up on Google for some music I was researching. It quickly highjacked my Safari browser with a popup that couldn't be clicked off. The best way I found to deal with it was to force quit the browser and unplug the internet connection. While disconnected, start browser and delete affected tabs and malicious cookies from: macosxcleaner.com, tutaudio.ru., best.aliexpress.com. I cleared these from my browser history as well. This method allowed me to retain the other open tabs upon restart. It's not a virus but a javascript that tries to trick you into paying fraudsters to"Fix" your computer. If you allow them in to do this then you've really compromised your OS and files. Below is the message from the popup. If this happens to you, Don't click "OK" and do what I did. From "http://macosxcleaner(dot)com": VIRUS FOUND The last website you visited has infected your Mac with a virus. Press OK to begin the repair process.
