Has my Mac been infected with ransomware?

Episode 1276 (2:07:52)

Victoria from Corvales, OR

Victoria has an 09 iMac that runs El Capitan, but she got bit by ransomware. Leo says that's odd because the only ransomware is called "Transmission" and it's been eradicated after only being out in the wild for a day through Bittorrent. She gets a pop up that says "your computer is infected," though. Leo says that doesn't mean she has ransomware. It's actually a phishing scam trying to get her to install malware. And she can't get infected by it anyway. What it does mean is that the website is infected and she should avoid it.
