Then, you can perform a search for ‘VisualDiscovery’. If you are infected with the adware, you will find this software program which you then have to uninstall.

It is important to ensure that the root certificate inserted by Superfish in our trusted certificates list gets deleted or removed completely (as this list impacts our secured browsing experience). To remove the Superfish root certificate, we can run the Windows Defender security software as Microsoft has updated it accordingly. We can also do this step manually by going to the certification manager window by typing “certmgr.msc” in our Windows search.
