How To Uninstall / Remove Lenovo Superfish Adware And Certificates From Your Computer

Lenovo is in the middle of a storm right now surrounding its inclusion of the Superfish software in all of its consumer oriented computers. The software injects ads into things like search results, but in doing this it effectively breaks all secure connections over the Internet by installing its own certificates. The ins and outs of why that is very bad indeed have been covered to death both here and by security researchers across the Internet. What’s important now is how to get rid of Superfish for once and for all.

The steps for removing Superfish from your Lenovo computer are rather easy, actually. It’s a simple case of uninstalling a piece of software and removing a certificate, but for the sake of complete clarification, we’ve broken down the whole process into a step-by-step guide so you don’t get lost in the process.


All set for removing Superfish? Simply follow the steps we’ve outlined below.

Uninstall Superfish

Step 2: Scan down the list of installed applications until you find ‘Superfish Inc. VisualDiscovery.’  Right-click it and uninstall it – or just click the ‘Uninstall’ button as shown in the screenshot below. If you’re prompted to enter an administrator password, do so.
