The steps to remove Superfish from your Lenovo laptop are relatively straightforward. The first thing you'll want to do is to uninstall Superfish. This is an app, so you'll be removing it the same way you remove any app. Once you're done there, you'll need to remove the Superfish-installed self-signed root certificate authority (CA). This is the most important part of this removal sequence, and it's a step you should not skip. It's easy to do, and you SHOULD do it right now.
