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.

  1. 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
  2. Open the Windows Start menu or Start screen and search for "Uninstall a program". Launch it.
  3. Right-click on "Superfish Inc VisualDiscovery" and select "Uninstall," then enter your administrator password.
  4. Next, you need to uninstall the certificates. Head back to the Start menu and search for certmgr.msc. Launch it.
  5. Click on "Trusted Root Certification Authorities" and open Certificates.
  6. Look for any certificates that include Superfish Inc, and right-click to delete them
  7. Restart your browser then head back to the link in step 1 to test your computer.
