How to Remove Superfish Adware from Your Lenovo Laptop
Majority of PC makers install unwanted programs on their devices, but Lenovo has apparently taken this trend to another level. The Chinese computer manufacturer preinstalled the Superfish adware on its own PCs, which according to the security researchers, not only places extra ads in the browser, but also leaves owners vulnerable to hackers.
The software tracks Lenovo laptop users’ searches and browsing habits and then use this information to show users additional advertisement on the sites they visit. The real concern, however, is that it makes up its own fake security certificates, resigning all SSL certificates presented by HTTPS sites with its own. This puts the users, with Superfish installed on their machines, at a great risk and makes them vulnerable to “man-in-the-middle” attacks without them being detected.
Being the nature of this Superfish adware, if you’re a Lenovo laptop user, you should be worried about it. But thankfully, it’s relatively simple to deal with this software. Follow the below steps to remove Lenovo’s “Superfish” adware:
- First, click on this link to find out if your machine is affected or not.
- If the machine is affected in Windows 8, click on search button and type “remove programs.”
- Select “add or remove programs” from the search results.
- In the list of installed programs, select “Superfish Inc. VisualDiscovery.”
- Select “Uninstall.” After several seconds, the program is gone.
But that’s not enough. It’s actually the root certificate that allowed it to contrive a secure web connection. So it’s as important to remove the root certificate. To do so:
- Go to C Drive > Programs > Delete the folders files associated with Superfish.
- Open search again and type in “Certificate.”
- Select “Manage computer certificates.”
- Agree to “allow this program to make changes to this computer.”
- Then a manager window will appear. On its left-side panel, click on the folder labeled “Trusted Root Certificate Authorities.”
- You’ll enter the subfolder called “Certificates.” Look for “Superfish, Inc.” on the right-side panel. Right click on it and then delete the certificate.
That’s it. To make sure you have fully removed the program, restart your browser and revisit the link in the first step.
Lenovo plans to release an automated tool that will remove the Superfish adware from affected PCs on Friday, said the company’s CTO, Peter Hortensius.
