How to detect and remove Superfish technology pre-installed in 42 Lenovo models?

If you own a Lenovo computer with model  number listed on the table at the bottom of this page and have not gone through the detection and removal process then it’s infected with a malware made by Superfish Inc.  The  malware injects visual ads on your browser, and in some cases approves malicious websites that may have the potential to capture critical data.



To quickly check if your Lenovo computer is infected with Superfish go to this website - https://filippo.io/Badfish.

If you have more than one browser installed, open each browser,  copy and paste the link.

If your Lenovo computer is infected you need to uninstall the Superfish VisualDiscovery program AND  the Superfish Inc.  trusted root certificate.


To remove the Superfish Program:
  1. Go to Control Panel
  2. Look for “Superfish Inc. VisualDiscovery”
  3. Uninstall

To remove the Superfish Certificate:
  1. On your keyboard press Windows key + R
  2. Type or copy and paste certmgr.msc
  3. Click on “Action”,  click on “Find Certificates”, type “Superfish”
  4. Left click on “Superfish” , click on delete



Re start your Lenovo computer and go to  https://filippo.io/Badfish website again to verify Superfish had been removed.
