SuperFish Removal Utility

SuperFish was pre-installed on a limited group of Lenovo branded notebooks beginning September, 2014. Lenovo recommends removing SuperFish and the SuperFish certificates from all systems.

This utility will completely analyze your system for this problem and remove the SuperFish application, associated registry entries, files and security certificates, if needed.
