Superfish

Superfish is like a bad guy who secretly sneaks in and watches everything you do on your computer without you knowing. It's kind of like a spy, but not the good kind of spy who helps people, but the bad kind who wants to steal your information. Superfish can do this by adding something called "adware" to your computer, which means it can show you unwanted ads and pop-ups. It can also access your private information, like your passwords and credit card numbers, which is really not good. So, it's important to be very careful about what you download and keep your computer protected with good anti-virus software.
