Lenovo accused of compromising user security by installing adware on new PCs

Leading PC manufacturer shipped computers containing Superfish software that could leave users permanently open to attack when using public Wi-Fi network

Lenovo, the largest PC manufacturer in world, has been accused of fatally compromising user security by installing an adware application on all its Windows computers as they leave the factory.

The software, called Superfish, purports to offer users a "visual search" experience. In actual fact, it injects third-party advertisements into Google search results and websites, without asking the user.
