Lenovo came under fire a few years ago for pre-installing adware called VisualDiscovery (developed by Superfish) onto new machines. Now that the legal dust has settled, the laptop maker has agreed to pay $3.5 million in fines to a 32-state coalition “to resolve their concerns” related to the nefarious bloatware app. In 2015, the worry was that the software performed a man-in-the-middle attack on supposedly secure connections and could be used to spy on encrypted communications. The company issued a tool for removing the software at the time.
