[How To] Find Out If Your Lenovo Is Infected With The Superfish Adware And Remove It

with 0 Comment
Users on Lenovo's forums have discovered that the Chinese company has been preloading some consumer PC models with a software called Superfish Visual Discovery. In short, the software tracks your searches and browsing habits (even on secure sites) and uses this information to place additional advertisements on the sites you visit. It's unclear what models have come preloaded with the software, although users have reported finding it on Lenovo Y50, Z40, Z50, G50 and Yoga 2 Pro models.




LastPass has created a Web tool that makes it easy to check to see if your computer is infected. You can check by simply clicking on this link.


If you’re affected by Superfish, you must first uninstall the program:



  1. Click the Windows Start button
  2. Search uninstall program
  3. Launch uninstall program
  4. Right-click on Superfish Inc VisualDiscovery and select Uninstall
  5. If prompted for administrator password, enter or provide confirmation



Then you must uninstall the certificates as well:



  1. Click the Windows Start button
  2. Type certmgr.msc into the Search box
  3. Click the certmgr.msc Program to launch it
  4. If prompted for administrator password, enter the password or provide confirmation
  5. Click on Trusted Root Certification Authorities
  6. Open Certificates
  7. Look for certificates mentioning Superfish Inc.
  8. Right-click on any Superfish Inc certificates and delete


To make sure you have fully removed the program, restart your browser and revisit the LastPass web tool.
