How to Test Your Computer and Remove the Superfish Software and Certificates
Thankfully, it's easy to test to see if your computer is affected by Superfish. We had a handful of Lenovo PCs to test on and all ours were clear, but it only takes a second to test yours, so it's worth testing regardless of what type of Windows machine you have. Uninstalling and removing Superfish is a bit more complicated, though.
- Head to this link (LastPass has a tool as well, if you'd like a second look) in Internet Explorer or Chrome to test if your computer has Superfish installed (it won't work on Firefox). If you get a No, you're good, if you get a Yes, continue onto step 2.1
- Open the Windows Start menu or Start screen and search for "Uninstall a program". Launch it.
- Right-click on "Superfish Inc VisualDiscovery" and select "Uninstall," then enter your administrator password.
- Next, you need to uninstall the certificates. Head back to the Start menu and search for certmgr.msc. Launch it.
- Click on "Trusted Root Certification Authorities" and open Certificates.
- Look for any certificates that include Superfish Inc, and right-click to delete them
- Restart your browser then head back to the link in step 1 to test your computer.
