If you have a Lenovo computer and you want to remove the adware using Windows Defender, make sure to disable any other antivirus you may have running. Go to Control Panel / Windows Update / Check for updates, and make sure to download the latest update for Windows Defender if it’s not already installed. Then go back to the Control Panel and launch Windows Defender, and perform a full scan of your system.

While Lenovo has published a set of instructions to manually remove Superfish from computers, the process can be a little hard to follow if you’re not a tech-savvy individual. However, the PC maker promise that will be releasing an automated tool to remove the adware completely on Friday.
