There's a lot more people using WinRAR that I imagined. For all you WinRAR users out there, note, there's a bug that could bite you. I moved on to 7-Zip, because good + free == great in my book.
Web searches such as this one show that an Ariana Grande RAR file with the same title identified by McAfee is currently circulating on BitTorrent download services. They’re also being advertised on Twitter. People should be reflexively suspicious of any file offered for download online.
I would really hope at this point that, everyone is at least somewhat suspicious of files offered for download online. Otherwise, someone has done you a great disservice. At the very least, you need to be practicing good bittorrent practices. Getting known good seeds from trustable sources. If you're playing in the seedy underbelly of society, then don't be surprised when your device is compromised 100 different ways.
