How to Get Shot of Lenovo’s Superfish Adware

I was interested to read an article that recently appeared on (link takes you to the full article) about Lenovo’s Superfish Adware.

Just in case you didn’t know, Superfish is an adware installed on Lenovo computers that tracks what you do so it can push adverts to you while you browse.

Annoying, but harmless, right?


The danger with Superfish is that it is a way for others to intercept your online communications and hijack your laptop to steal your personal information.

The article went on to say that Lenovo said it:

“…had removed Superfish from the preloads of new consumer systems in January 2015”

It also stated that Superfish was never installed on ThinkPad notebooks, Lenovo desktops or its smartphones. Users with enterprise products (e.g. servers or storage) are also unaffected.

Just in case you’re the owner of a Lenovo machine and are beginning to get a bit twitchy, here’s how to remove Superfish:

  1. Check if Superfish is active on your computer: Go to Superfish CA test to check if it is active on your computer. If it’s not showing up it may be there but inactive, so do step 2 anyway
  2. See if Superfish is installed on your computer: Click the Start button and search for “Add or Remove Programs”, also called “programs and features” if you’re using Windows 10. Scroll down the list and see if you have “Superfish Inc VisualDiscovery” installed on your computer
  3. Uninstall Superfish: If you have Superfish Inc VisualDiscovery installed, right click and select “Uninstall”. Follow the on-screen prompts, entering an administrator password if prompted, and you’ll be free from the first part of Superfish’s gaze
  4. Search and remove old Superfish web certificates: Click the Start button and search for certmgr.msc and launch it – you may be prompted for an administrator password
  5. Locate Superfish Inc certificates: In Certmgr, click on “Trusted Root Certificates” and look for any certificates mentioning Superfish Inc. Remove them by right clicking and selecting “Delete”
  6. Restart all open browsers/restart computer: Make sure you close down all your browsers when complete, or restart your computer if you’d rather be extra safe, then just re-open them and you should be all clear of that nasty Superfish infection

Once that’s done you should be able to browse in safety.
