Lenovo, the World’s largest PC maker, had pre-installed a virus-like software which makes the computer vulnerable to the hacking attacks. These laptops were recently shipped with a controversial software, known as Superfish, which was billed as a free “visual search” tool to find products online by scanning images and thus presenting similar products.
This software tracks your searches and browsing habits and shows extra advertisements on websites. Superfish works as an intrusive ad and hijacks and throws open encrypted connections helping the hackers to target you.
Lenovo has accepted the shipment of laptops with Superfish between September and December 2014. The actual number of affected laptops is unknown and since the pre-mentioned time period, the Chinese PC manufacturer has shipped more than 16 million desktops and laptops.
In a statement, Lenovo has told about the stopping the preloading of Superfish since January but it added that Lenovo had “thoroughly investigated this technology and (does) not find any evidence to substantiate security concerns.”
Here is a list of the models affected by Superfish:
