Superfish, was preinstalled (starting Sept 2014) by Lenovo on a number of their consumer laptops, is detected as being Adware, Trojan, and Riskware by at least 23 AntiVirus & AntiMalware scanners

Superfish visual discovery software was preloaded onto Lenovo consumer level notebooks beginning in September 2014. Per the Lenovo News Release: “The goal was to improve the shopping experience using their visual discovery techniques.”

The preinstall of Superfish on consumer level laptops, was terminated by Lenovo in January 2015.

Superfish was apparently never installed “on any ThinkPad notebooks, nor any desktops, tablets, smartphones or servers; and it is no longer being installed on any Lenovo device.”. Enterprise level hardware (like Servers and Workstations) was also “not” affected. Only “consumer level” laptops were apparently affected.
